Judd 410 is a pattern for a Three-Cent Nickel, but it looks so much like the adopted design that the two are sometimes confused. For instance, Lot 726 in the May 1996 sale of the Eliasberg Collection, which was supposed to be a regular issue 1865 Three Cent Nickel, was actually a Judd 410. Neither Eliasberg nor the previous owner, John Clapp, caught the error. The net result is that Eliasberg did not own a regular issue 1865 Three Cent Nickel, putting an asterisk on his claim to have had a complete collection of U.S. coins.
On Judd 410, the date is higher in the field than on the regular issue and, on the reverse, the ribbon ends merge with the denticles (on the regular issue, the ribbon ends are clear of the border).
An estimated dozen Judd-410's exist today, although the number of times that Judd-410's have appeared at auction might suggest otherwise. In reality, some examples have appeared and reappeared at auction numerous times before finally settling into a permanent collection.
The best example of which we are aware is the PCGS PR67DCAM in the Bob Simpson Collection.
