BOLIVIA. 4 Reales, 1770-PTS JR. Potosi Mint. Charles III. PCGS EF-45. KM-49; Gil-P-4-4B; cf. Yonaka-P4-70C; Cal-928. Colonial bust edge variety; circles and squares, Small J with Large R in Assayer's initials. This very interesting and EXTREMELYRAREexample displays even wear and attractive mottled gray patina with a slight iridescent sheen that pops out when tilting in the light. The surfaces are relatively smooth with signs of handling consistent for the grade exhibiting only minor marks or abrasions. This wholesome looking piece offers much originality and is pleasing to the eye certain to catch the attention of even the most advanced of collectors. Close inspection of the edge reveals a characteristic not normally associated with this type for any denomination. The usual edge design found on pillar coinage is the "Tulip edge", which was used on all denominations and mints. In fact, the "Circle and Square" edge used on the present piece was not put into production until the bust coinage of Charles III in 1772-73 and would continue up through the Wars for Independence. The dies appear to be fresh with little in the way of degradation from prolonged use. Somewhat perplexing, this mismatched combination of coin design and security edge seems to insinuate that the last year of production was extended longer than normal. More research is needed from the specialist to come to feasible conclusion as to why and how this could have happened. Estimate: $2,000 - $3,000. Provenance: From the Pat Johnson Collection.
