Argentina
Republic Peso 1883 MS62 PCGS, Buenos Aires mint, KM29. Lustrous Mint State with old golden patina and minor surface contact evidence preventing a higher designation. The key date of this type, scarce in any grade and conditionally very rare in this most engaging preservation. Currently the only Mint State example certified by either major third party grading service and a coin that should thus attract strong bidding attention.
Estimate: 3000-4000 USD
