Weather
April in Schaumburg is a spring transition month, not a warm one. Typical daytime highs run about 12-18 C (54-64 F) and overnight lows about 2-7 C (36-45 F), with rain on roughly a third of April days and occasional gusty cold fronts. A late-season wet snow flurry is possible early in the month. Pack layers, a waterproof outer shell and closed shoes for long hours standing on concrete bourse floors. This is a climatological range, not a forecast: check a 10-day forecast for Schaumburg before you fly.
Plan for the climate
Check temperatures and pack accordingly
Venue connectivity
U.S. mobile networks use GSM/LTE/5G and are compatible with most European and Asian handsets; an eSIM or prepaid SIM from a U.S. carrier is the simplest option for a four-day stay. Wi-Fi is normally included at Schaumburg hotels and is usually available in convention center public areas, though hall Wi-Fi can slow down during busy periods. Electricity is 120 V at 60 Hz with Type A and Type B plugs, so travellers from Europe, the UK, Australia and much of Asia need a plug adapter and, for some devices, a voltage converter. Card and contactless payment are accepted almost everywhere, but small cash amounts remain useful for bourse purchases and tips.

Cultural notes
Useful information to help you have a smooth and respectful visit.
Dress on the bourse floor
Numismatic shows are smart-casual, not corporate. Dealers usually work in a shirt or polo and comfortable shoes; collectors dress casually. A jacket is only needed for an auction dinner or a formal club event.
Handling etiquette
Never reach into a dealer's case or pick up a coin uninvited. Ask, and the dealer will hand it to you or place it on a velvet pad. Hold coins by the edges, keep them over the pad, and return them to the same spot.
Price negotiation
Asking for a better price on a multi-coin purchase is normal and expected, but a polite, informed offer based on grade and recent auction results works better than a lowball. Cash and card are both accepted, though some dealers prefer one over the other for small lots.
Tipping and service
Tipping of 18-20 percent is standard in U.S. restaurants and bars, and a dollar or two per drink at the hotel bar. Hotel housekeeping and shuttle drivers are usually tipped a few dollars.
Greetings and small talk
A handshake and first name are normal in the U.S. Midwest. Conversation usually opens with where you travelled from and what you collect before any price talk, and dealers appreciate a specific want list rather than a general browse.
Security and valuables
Keep purchases in a zipped bag worn across the body, do not leave coins unattended on a table, and use the hotel safe for high-value material. Ask the hotel about in-room safes or safe-deposit boxes for dealer stock.
Local tax and receipts
Sales tax applies to many retail purchases in Schaumburg, while coin and bullion treatment can differ by transaction. Request a written receipt with the coin's description and grade from every dealer, both for tax and for insurance.

Answers
Frequently asked
When and where is the 2027 CSNS convention?
The convention is scheduled for 21-24 April 2027 at the Renaissance Schaumburg Hotel and Convention Center in Schaumburg, Illinois, a northwest Chicago suburb near Woodfield Mall. Check csns.org for the final hall assignment, show hours and any last-minute changes before travelling.
How much does admission cost?
Admission is listed at USD 15 for a daily ticket and USD 30 for a three-day pass. Bring a card and some cash, since bourse purchases from individual dealers are often settled by card but small notes are still useful.
Is the Schaumburg show open to the public?
Yes. General admission tickets are sold per day, so the bourse floor is a ticketed public show rather than a dealer-only trade session. Confirm any early-entry or dealer-preview hours on csns.org before you plan your arrival.
Which airport should I fly into?
Chicago O'Hare International (ORD) is the closest major gateway, roughly 25 km and 25-40 minutes by car depending on traffic. Chicago Midway (MDW) is a secondary option at about 45-60 minutes by road. Both connect to Schaumburg by rideshare, shared-ride shuttle or a combination of CTA and Pace services.
How do I get from O'Hare to the Schaumburg convention center?
Rideshare or taxi from ORD takes about 25-40 minutes off-peak and is the simplest option with a coin case. Shared-ride shuttles serve Schaumburg hotels, and Pace buses plus Metra's Milwaukee District West line reach Schaumburg for passengers travelling light. Fares and schedules should be checked on the day.
Is parking available at Schaumburg hotels?
Several Schaumburg properties, including Hyatt Place, Embassy Suites, Courtyard by Marriott and Four Points, advertise free or included parking. Surface parking around the Woodfield and convention-center area is generally plentiful, but confirm the rate with your hotel when booking.
What should I bring to a coin show?
Bring a want list with dates, mintmarks and grades, a loupe and a reference guide or price app, a credit card and some cash, and a secure bag for purchases. Dealers appreciate buyers who know the grade and variety they are looking for.
Can I sell coins or have a collection appraised at the show?
Many bourse dealers buy collections on the floor and some offer informal opinions, but policies vary by dealer. Ask before handing over material, and get any offer in writing. For large estates, compare at least two dealer quotes or an auction-house consignment estimate.
Can I photograph dealer displays?
Ask the dealer first. Most allow photos of a specific coin for reference, but flash, crowded cases and photographing price tags without permission are unwelcome. Follow any venue or organiser signage in the bourse hall.
Is the venue accessible for wheelchair users?
The Renaissance Schaumburg Hotel and Convention Center is a modern convention property with level halls and lift access, but aisle widths in a busy bourse can be tight. Contact the venue or the organiser ahead of your visit for specific accessibility requests.
What is the weather like in Schaumburg in April?
April is changeable spring weather, with typical daytime highs of 12-18 C (54-64 F) and overnight lows of 2-7 C (36-45 F). Rain falls on roughly a third of April days and a late cold snap is possible, so pack layers and a waterproof jacket.
How many hotels are near the convention center?
A Google Hotels search for the 21-24 April 2027 dates returned 115 results in and around Schaumburg, from economy IHG and midscale Marriott and Hilton brands near Woodfield Mall to airport hotels along the O'Hare corridor. Book early because suburban Chicago hotel rates rise when large events are in town.
Glossary
- Numismatics
- The study and collection of coins, paper money, medals and related objects, covering grading, attribution, minting history and market values.
- Bourse
- The dealer trading floor of a coin show, where dealers rent tables and collectors buy, sell and trade coins face to face. At the CSNS convention this is the main hall where the bourse tables sit.
- Obverse and reverse
- The two faces of a coin. The obverse is normally the side with the principal portrait or design (often called heads); the reverse carries the denomination or secondary design (tails).
- Sheldon scale
- The 1 to 70 grading scale used across U.S. numismatics, where 1 is About Good and 70 is a flawless Mint State coin. Most circulated coins fall between 4 and 58.
- Mint State (MS)
- A grade band (MS-60 to MS-70) for coins showing no trace of circulation wear, with the numeric suffix describing strike, lustre and surface marks.
- Slabbed
- A coin sealed inside a tamper-evident plastic holder with a grading label from a third-party grading service. Slabbing fixes the grade and authenticates the piece, which affects resale liquidity.
- Raw coin
- An ungraded coin still kept in a flip, folder or capsule. Raw coins are bought on the buyer's own assessment of grade and authenticity.
- Third-party grading (TPG)
- Independent authentication and grading companies whose holders and labels the market recognises. Dealers at the bourse typically price slabbed and raw coins differently.
- Bullion
- Coins, rounds and bars valued primarily by metal content rather than collector rarity. Premium over spot depends on metal, weight, mint and demand.
- Proof
- A specially struck coin with mirror-like fields and frosted raised design, made for collectors rather than circulation.
- Key date
- A scarce date and mintmark combination within an otherwise common series, such as the 1909-S VDB Lincoln cent, which carries a large premium over other dates.
- Type set
- A collection holding one example of each design type in a series or era rather than every date and mintmark.
- Error coin
- A coin with a manufacturing mistake, including doubled dies, off-center strikes, clipped planchets, wrong planchets and repunched mintmarks.
- Planchet
- The blank metal disc that is fed into a press and struck to become a coin. Planchet flaws and clips are collected as error varieties.
- Toning
- Natural colour that develops on a coin's surface over decades of storage, ranging from pale gold to deep album toning. Original toning is generally preferred to artificial colour.
- Exonumia
- Numismatic material other than coins and paper money, such as tokens, medals, badges, elongated cents and political campaign items.
- Scripophily
- The collection of old stocks, bonds and other financial documents, valued for engraving, signatures and corporate history.
- Cherrypicking
- Spotting an underpriced variety or better date in a dealer's stock when it is priced as a common coin. Success depends on knowing die varieties and reference guides.
- Buyer's premium
- The percentage added to the hammer price of an auction lot, payable by the buyer on top of the winning bid. Rates vary by auction house.
- Flip
- A 2x2 inch cardboard holder with clear windows used to store and label individual coins. Dealer stock and collector duplicates are usually sold in flips.
