Yes, Numista is Awesome, anyone will be able to find out what coins they have, we will no longer be able to get great deal off of people who don't know what they have, but on the flip side perhaps more people will find an interest in coin collecting and that is the bigger goal.
I only ever found one guy selling a nice bag of coins at a good deal anyway.
Taking a break from swapping for a while, but still interested in pre 1799 Spanish coins, I will make time for that!
