I'm not sure which region of the state you're in. Here's one for the northeastern part. http://www.ohiocoin.com/index.htm
If you click on the link, over on the left side there's a link to the location map. It's on I77 just south of Cleveland.
What did you 'Bump' the thread for? Looking for another show? Why not ask anyone know of any others? Quick Google search would have given you results...http://www.coinshows.com/ohio.html
My point was, rather than post Bump, which is just dumb in the first place, post the question again... Anyone know of any more coin shows coming up, or anyone got any new information... Also, my quick google search lists tons of sites for coin shows in Ohio.
Been there too they only list the main show in the capital. I'm trying to find smaller shows but thanks for the info.
Though you have to check weekly but this what I use. http://numismaster.com/ta/inside_numis.jsp?page=CoinShowsCalendar Just click your region
Checking weekly might help with new ones that pop up, but you can check for future events. I just confirmed the EAC convention in Newark OH in May on that site.
