I would like to repeat what others have said, just for emphasis. Just because a seller lists a coin for a very high price does not mean that the coin is worth what they are asking. It also does not mean that they are actually selling any coins at that price. (hopefully not). Etsy is probably the worst place on the web to buy coins. For every legitimate seller, there are hundreds of scammers and thieves who are hoping to make a big score off some unknowing newcomer. My advice: stay away from Etsy and other similar places when looking for coins to buy, or when trying to determine the true value of your coins. Use patience, and do some diligent research before trying to buy or sell anything. The coins posted above would be fun pocket change finds, considering that they have been around for more than half a century, but honestly, they are only worth face value.
And if I haven't already said so, "Welcome to the forum."
