1962 Philadelphia Proof Set In Original Envelope

Many of the original mint set envelopes were never sealed even though the envelopes were gummed. Time and humidity can cause them to seal all by themselves. Sets with damaged envelopes frequently have them replaced with modern reproductions. IMO a sealed envelope is nothing but a detriment since you cannot see the condition of the coins at all. Who really wants to risk the chance of selling a nice cameo set under value but never knowing because the envelope is sealed? This is a running scam on ebay to make people think that they actually have a chance to get a cameo set but in reality the seller knows exactly what you are getting and it won't be cameo coins

Thanks for the info. I did not pay much for them so either way I would not be out much. I opened them and they appear to be very nice coins. I may look at rolling the dice and getting the Franklin slabbed. I am pretty new to this and consider it a learning process. This forum is great help for that.
