Just for fun, by that point though it's pretty reasonable to think you'll be able to sell the coin on multiple planets or at least the moon as well. Besides by 4019 $10 will probably be like a quarter today anyway
Who cares that the coin will never be worth much to others? The fact it was apparently owned by your father and this means something to you also means that in this context it should be priceless... to you. Just don’t expect any future windfalls and you’re good.
