First, welcome to the neighborhood! It looks like you might have a nice specimen missing the obverse clad layer, but I'll wait to see what @Fred Weinberg and @paddyman98 have to say. Many Mint errors are only worth what someone is willing to pay for them, so let's see what they say. FYI ~ It is always best to start a new thread when asking about another coin. (This thread was started about 9 years ago.) Chris
