Watch List notes:

Lot of two San Jose, Costa Rica, Banco Central, 100 colones, 5-10-1990, serials F18110235, duplicated serial numbers error, PCGS Choice UNC 64 and Choice UNC 64. SCWPM-254a. This major mistake at the printers resulted in two identical notes sharing the same series letter, date, and serial numbers - a pair that shouldn't exist! And, interestingly enough, they were also graded the same Choice UNC grade. Pedigreed to the Tamarindo Collection of Costa Rican Error Coins and Paper Money.
($300-450)
