Found old coins

I found a bunch of old coins and foreign Money. I’m from Arkansas. Where can I go to see if any of these are worth anything

you could search google maps for "coin and stamp dealer" or
you could save yourself a long drive, just take a picture and post it in this thread

This site has prices ...

or go to eBay and look at Sold prices.

You could also research them, and add them to your collection right here on Numista, and can see what the "swap values" are for many of them. I have found for many coins the swap value is roughly between what dealers would pay for a coin and full blown retail.
