Coin Dealers In Illinois

I'm interested also....

Northwest side of Chicago and surrounding suburbs.

Lots of coin shows in Northern Illinois. Many dealers there also have coin stores in the area.
One in a town called Schaumburg on the 1st Sunday of every Month.
Biggest one is in a place called Countryside. It is just South of Lagrange almost on the corner of LaGrange Road and Joliet Road. 2nd Sunday of Every Month. Next one is Sunday, October 14th. Sometimes from 80 to 100 dealers.
October 21st at Cicero-Berwyn. 6630 West 16th Street, Berwyn, Illinois
October 21st at Itasca, Illinois. On Irving Park Road, in a Holliday Inn, just West of Itaska commuter train station.
Usually there are flyers from coin stores on tables in those shows.

Absolutely. And no parking fees, No admittance fees, No taxes of any kind. No postage, handling, insurance fees either. No Pay Pall or ebay fees. Haggling over a price is almost mandatory. Remember that all such shows are basically just specialized flea markets.
In Illinois there are coin shows, dog and cat shows, computer shows, electronic shows, camera shows, gun shows and on and on and on. All are basically the same where you can haggle prices down. It is sort of expected. And expected to the point where mose dealers raise their prices knowing people will haggle them down.
At a coin store the dealer must pay for rent, electric, phone, gas, water, possibly help and lots of other expenses. Then still must use some of the profits for his own home. At a coin show, just the table rental.
