A 1/3 farthing coin? Egad, that was a terribly small denomination.

I know! There was even a 1/4 farthing coin, but it was never legal tender in the U.K. Again, it was intended for a colony.

That from an age when money slowly increased in value over time. How's that for a vignette?

Speaking of low denominations, the early Republic saw the Mint issue a half-cent coin. Despite its small monetary value, it was about the size of a quarter. The switch from the large cent to the small cent in 1858 put the kibosh on the half-penny. The original large cent was more than an inch in diameter.

27-29 millimetres for all you metric guys :)
