No, your plain-jane rounds are worth a % over spot, no more, because that's what you and the seller agree to exchange for them.
THE price of a one-ounce Liberty Dollar round is $20, because that, or a discounted rate for bulk purchasers, is what the seller is offering to the public. THE price of a one-ounce US Mint silver dollar proof is $30, or some discounted rate for distributors, because that's what the sellers are offering to the public - if you're lucky - this guy is offering a 2006 silver eagle proof for $43.70.
Saying that the ounce price of a 500-ounce ingot in New York for immediate delivery is THE price of silver is like saying that the spot price of a bushel of wheat is THE price of whatever bread can be baked from it.
What is THE price of this ounce of silver?
People just need get a clue about the market in fungible commodities and get over their worship at the feet of the spot price.
Oh brother, this is a waste of time now. You think the sound of your spinning wheels is a symphony.
Actually, the market sets the value. If I take a bar of gold to a car dealer and say “ I will trade this bar for that car”, and he takes the deal, I haven’t used legal tender to buy the car, and apparently, he felt the deal was good enough to sell me the car. I could trade him property, or a vintage Volkswagen. If I took a Ron Paul dollar into the Dollar Store, they don’t have to take it, but they could. I don’t see that this is all that bad.
