I don't know if there will be a new key by convention time but I've noticed something in the past. With every name change there are at least two changes. The first is ™ after the new logo/name and the second is ©. Sometimes there is even a change to ®.

Anyone have older Nevada or Hawaii elongated coins to trade or sell? They're also known as smashed pennies.

BTW that's not my email above. My email is:
