Some good older coins that you have.
I'd say just hoard them and keep them for 20 years plus by tnen they could be worth more.
I know a person a few years past detecting in a park that he found a 1921 fishscale nickel.
He got $5000.00 for it.
He sold it to dealer who sold it for $8000.00 shortly after. Very few minted and circulated.
