Tough call between this And this. No I don't own the second came from pcgs. I can agree with Chief on the gold small eagle too be my third choice
I don't have examples to send pics of and the ones I do have aren't of the quality that gets posted here, but these are some of my favorites. Seated Half Dime 1863 Buffalo Nickel Barber Quarter SLQ Franklin Half Texas State Quarter (just because I'm from Texas)
Curious that no modern coin reverses have been posted so far. I'm hugely in favor of changing the designs of all the current circulating coinage.
