Are GOLD PLATED Collectibles a wise purchase?

It is not a wise purchase. A wiser purchase would be to spend your $10 on an uncirculated Mercury dime. You should be able to buy a 1941-44 on ebay for about $10 or maybe even less. The value if history is any indication should double about every 10 years or so. Maybe in the future even more rapidly. I remember when one could buy uncirculated buffalo nickles for $6 each. Can't buy them for anywhere near that today--more like $20 or higher.
