This specimen was lot 73430 in Stack's Bowers Collectors Choice sale (Costa Mesa, CA, October 2025), where it sold for $312. The catalog description<sup>[1]</sup> noted, "[[Bolivia|BOLIVIA]]. Cob 2 Reales, 1657-P E. Potosi Mint. Philip IV. PCGS FINE-15. From the Richard August Collection." Assayer Rodas was brought in from Spain to restore the purity of the cobs struck at Potosi which had been debased as low as 0.700 fine. He did improve the quality but his product still did not meet the legal standard. He was sacked and replaced by Ergueta, who introduced the new "pillars and waves" design which would show the date and assayer's initials on even the worst strike. Ergueta served 1651-78. Cayón reports a variety with 1657 on the obverse and 1656 on the reverse (Cayón-5966).
