1920 Standing Liberty Quarter Struck on Peru 20C Planchet
NGC MS 60 FH Unique

This is the only known Standing Liberty Quarter struck on a foreign planchet for the entire series. Standing Liberty Quarter Off-Metals are so rare that there are only a handful known struck on any other planchet. This unique off-metal is a very recent discovery and was unknown to the numismatic community and not listed in any reference book or catalog.

This is one of the most incredible and rare major mint errors that I've ever had the pleasure of offering for sale. It is an extreme rarity and would be the centerpiece of any mint error or Standing Liberty Quarter collection.

"S" Walking Liberty Half Dollar Double Struck 50% Off-Center on 25¢ Planchet

This Walking Liberty Half Dollar has to be the most incredible mint error in the series. Not only is it struck on a silver Quarter planchet, it is also double struck. The second strike is 50% off-center with a uniface obverse. Even though there is no date, it was struck at the San Francisco Mint since the "S" is clearly visible. It is in gem mint state condition and was recently certified by PCGS. It is also the cover coin of Issue 24 of Mint Error News Magazine.
