Nice forgery collection with a few real items .
The problem on sell items like this ,if your not sure ,you sell them as forgeries at 2 or 3 dollars a piece . If you think and then you sell them as real stamps ,your looking for serious problems .You will end up giving them away to the buyer after you refund their money .The firms like
ebay and others take a very harsh view if you are selling fakes as real stamps.
