For four decades, there was just one unique Proof 40% Silver Ike Dollar blank known to the numismatic community. This mint error was certified, authenticated and encapsulated by PCGS. Fred Weinberg is the PCGS Consultant for authenticity for all mint errors submitted to PCGS. He authenticated this unique Proof Silver Ike Dollar blank planchet.
Recently a small hoard of San Francisco major mint errors in proof and mint state were discovered. Included were these fifteen (15) proof blanks. This is exciting because it is amazing that new discoveries surface and are authenticated and become available for coin collectors to enjoy owning a part of history. Fred Weinberg stated that "these specific 15 pieces of NGC-certified 40% silver planchets, from the San Francisco Hoard, are in my opinion, proof planchets like the single PCGS certified Proof Planchet."
Proof Ike Dollars struck in 40% Silver were issued from 1971 to 1976. This is one of the most popular U.S. Coins collected. All Proof Ike Dollars were struck, sold and shipped in official U.S Mint sealed packaging. These recently discovered proof blanks have the same pebbled surfaces that are known on U.S. proof blanks. NGC authenticated and encapsulated these 15 blank planchets, and noted on the insert that these were from the 'San Francisco Hoard.'
The discovery coin, a PCGS certified Proof 40% Silver Ike Dollar blank, was in Fred Weinberg’s personal collection and I recently purchased it from him. Considering that a Presidential Dollar blank with the edge lettering was also being offered by Fred Weinberg for $8k and Silver Dollar blanks sell up to $2k each, this unique proof silver blank was an exciting purchase.
I’m offering this unique group of 16 Proof 40% Silver Ike Dollar Planchets for the first time. This includes the PCGS discovery coin. This group is reasonably priced considering what other unique blank planchets have sold for. In addition, unique discovery mint error coins have always brought a substantial premium and this discovery coin is included in this group.
This is one of the 15 Proof 40% Silver planchets certified by NGC:
