I recently received these pictures, They are cash refunds of Tide and Cheer detergent each envelope has Canadian quarters and nickels sealed inside. I know they are from the 1950's so the quarters are 80% silver. So I know the quarters are worth more then face. But does anybody know if these envelopes with the sealed coins inside in of them selves has any value?
that would be hard to say, because the collector value would not be strictly based on numismatics. I would image that there would be some sort of premium to those people who collect older advertisement materials. From the aspect of a coin collector, however, I doubt that there would be much premium to be had, except (as you pointed out) that the dates inside would have to be pre-1950's. I would hate to see them opened up if there were a market for such things, though.
You are wise to ask first. As a rule, I try not to do anything that could impact the value of something. In this case, there MIGHT be a value to sealed envelopes. The value of the coins is not decreased by leaving them in there, so I would probably not open them up. In other words, whatever the coins are worth outside of the envelope, they are worth at least that much inside the envelope. However, if I had doubles I might be tempted to open one and see what was inside. If these were new coins when they were sealed, the paper might have created some fantastic toning.
