Theoretically, a coin's "fair market value" has three components:
- the
face value, the amount of money you'd get for your coin if you banked it. If a coin is demonetized or obsolete, then the face value is zero.
- the
bullion or scrap metal premium - the the difference between what the bank will give you, and what a scrap metal merchant will give you. Note that for many modern circulating coins, this value should always be negative, otherwise the government is losing money making them.
- the
numismatic premium, the difference between what a scrap metal merchant would pay and what a coin collector would pay. This should never be negative, otherwise coin collectors would find that people will not sell coins to them.
Coin collectors and dealers
should adjust the prices of their coins up and down with the bullion price. If they don't, it's because they're either lazy or because, as in justcarls example of the 1916D dime, the numismatic premium is so much higher than everything else it doesn't really make much difference.
Lets look at your two examples.
The
Presidential dollar:
- has a face value of $1
- has a scrap premium of about -80 cents
- has a numismatic premium of a dollar or more, depending on type and condition.
so it's final value is more affected by face value, rather than scrap value, and the numismatic premium outweighs them both.
The
ASE:
- has a face value of $1
- has a bullion premium of $29
- has a numismatic premium of a couple of dollars or more, depending on date and condition
so its value is dominated by the bullion price.
