1907 P$10 Gold, J-1901 MS

The so-called "Wire Edge with Periods" variety designed by Augustus St. Gaudens. This was formerly referred to as J-1774 in earlier Judd editions.

Research by Roger Burdette, that later appeared in the May, 31 2004 edition of Coin World has determined that 542 examples were struck, 500 in late August to early September 1907 and an additional 42 between September and December 31. 70 of these pieces were later melted. All of these were circulation strikes and not patterns.

His research has discovered that true patterns for this design do exist and they were struck using a hurriedly made edge collar which has 2 large stars at one end of the tri-partite collar as shown below.

Only those with this edge should be called J1901/P1995. The rest should be called 1907 Wire Edge with Periods and listed as regular circulation strikes.

3 examples with this edge are in the Smithsonian. It is not known if there are any others.
