I can't believe anyone would pay $120 for a $24 piece of silver. I know it cost you some extra money to get them pressed, but that's crazy.
I presume you are not a coin collector based off of this comment. I have seen 1 ounce gold coins appraised at $20k +. Hope you were seated when you read this, lol.
The difference is that this is not a collectable coin. At the time they were minted, those same coins you are talking about were sold at appropriate value. It's not right to start out selling a coin so far marked up because someday it might be valuable beyond it's value in silver. Even pandas, where we know the price is going to be over $100 in 5-10 years time are sold at a reasonable price now.
