Puerto Rico (under Spain), 1/4 dollar, fleur-de-lis countermark (1884) applied twice on a Spanish bust 2R (probably Madrid mint), Charles III, 1781, very rare (unlisted) combination. KM-unl. 5.01 grams. One countermark full and the other nearly so on a very worn host (Good/Fair), yet with clear date and enough detail to tell it is a Spanish issue (the first we have heard of for this countermark).
Estimate: $300 - 450
