Pre-1965 dimes, quarters and half dollars. Avoid silver dollars, the alloy is a bit different. Silver fractionals work well too but US coins are easily recognizable.

1/10 oz gold fractional are good for large purchases but command too high a premium today.

Just my two cents, pun unavoidable.

This is my choice too and I think the best one.
