One of only nine produced, this was a test alloy produced by Dupont for the United States Mint as a replacement for the 90% silver being phased out that year.  While this composition in particular was not approved, Dupont proceeded to produce all of the quarter planchets for the year 1965.

The Feuchtwanger Cent was an attempt by Lewis Feuchtwanger during the 1830-40's to help alleviate the shortage of small denomination coinage.

Made of argentan, more commonly known as German Silver, the coins were produced of an alloy of copper, nickel, zinc, tin, and trace metals.

This cent design was presented to Congress in 1837 for approval as legal coinage.  Despite Congress' denial, Feuchtwanger continued to produce and circulate these tokens out of his New York City pharmacy by the thousands until 1844.

As rare as the famous 1913 Liberty Nickel, at a fraction of the price.  Only six examples are known to exist and this is the finest one.  The 1913 Liberty fetched $5.2 million in a recent auction.  An 1838 example of this quarter fetched $184,000 in January 2007 at the Heritage auction (see chart here).

According to the NGC census, NGC has graded two of these such coins.  One is a PF-65 Cameo, while this is a PF-65★ Cameo.

A highly sought-after issue of the 1932 quarter, this coin is in stunning shape and exhibits full mint luster.  As rare as the 1932-D, but at the moment, only being sold for a third of the price.

This coin is currently sub-$1000 priced, which is difficult to locate just about anywhere.
