Watch List notes:

Lot of two counterstamped Costa Rica 1R on Spanish colonial cob 1R of the 1700s: 1846JB (Type IV) and 1849JB (unlisted Type, very rare). KM-47 and unl.. 4.68 grams total. This pair illustrates the differences between the common 1846JB counterstamp (Type IV) and the very rare 1849JB counterstamp (unlisted). Beginning in 1846, the lack of Costa Rican coinage led to the counterstamping of circulated Potosi and Lima cobs. By mid-1849, however, the practice was banned in favor of circulating newly issued Costa Rican coins and countermarked Central American Republic pieces. Still, some 1849JB-counterstamp examples are known (sources say ten known). Both coins in this lot are counterstamped on worn hosts, likely from Potosi, the 1846JB counterstamp Fine with most details visible, small planchet flaw or host coin design interfering with the legend and date on the sun-over-mountains side, and the 1849JB counterstamp Very Fine with a clear legend and date "1849".

Estimate: $1500-2250
