I've been to a few coin shows over the past year and a half; 2 of them several times. Out of the shows, the smallest one was the show in Bloomington, Indiana on April 12th of this year; there were 32 tables and around 20 dealers, including me. What's the smallest coin show that you have attended? I've seen pictures of some but have never heard of the experience.
I have a local coin show called the Montgomery Co Coin Show that is monthly; I only attend a few times per year because it is always the same dealers with the same inventory. I don't recall how many tables there are, I want to say 50, maybe a little more.
You are correct, they have the Montco & Trevose shows combined on one Facebook page now called the BuxMont Coin Shows. The Trevose show is just a little too far away for me, like an hour drive.
We have coin shows in Raleigh about six times a year. One or two of them are in smaller venues, and while I don't remember exactly how many dealers were at the last one I attended, I'm thinking 12 was probably about the most it could have been. I eventually stopped going to those; it wasn't worth the 20-minute drive each way.
