Fortin 101, A-1. This issue is extremely difficult to locate in problem free VF or better. Only 19 submissions have achieved a higher numerical grade than this one as of June '11. From Rich Uhrich.
Fortin-104b. small o. Ex: Bender, Srotag, SBG Treasures of the SSNY sale '09. CAC.
Fortin 101, A-1: The date is punched very high with the 1 and 8 in the base of the rock. The mintmark is the large 'o' variety. There are 2 other mintmark sizes with the small o being rarest according to Gerry Fortin's reference.
Fortin 101: only one die pair discovered to date, though Breen lists a small o variety and the mintage would suggest a second pair would be needed. Few 1851-o dimes were saved from circulation and a mere 10 mint state examples have been certified by the 2 major services. There is only one known gem in a 65 NGC holder. A total of 50 submissions have occurred at NGC and PCGS combined.
Fortin 101. The date is high and slopes downward from left to right. This is the only known obverse. The mint mark is large, thin, and well centered. It is the more common of 2 known reverses.
Fortin 102. Even date, large thin MM. Ex: Kennywood, Branch Mint Collection. 1/0 at CAC.
Fortin 102. High date with slight slope downwards. The MM is the more common large variety. A diagnostic spur is seen at 8 o'clock on the 'O' of OF on the reverse. A real luster bomb that these crappy iPhone images fail to capture. Would easily + if resubmitted. Holdered >20 years ago. CAC.
Fortin 101: the only known die pair. This issue is actually rather elusive as evidenced by its mintage of 299,000. In Brian Greer's Complete Guide to Liberty Seated Dimes, the 58-o is known for soft strikes especially at the head, breast , and tail feathers. Luster is usually subdued on mint state pieces.
Fortin 103: medium level date, open 5, with die chips seen about star 5, medium o. A-2, G101. With a limited original mintage of 480,000 coins and a poor rate of survival, the 1859-o is a scarce coin in all mint state grades. This well-struck example is adorned in emerald, citrine, and amythest hues Ex. Superior Worrell Collection Lot 374 Sept 1993.
Fortin 106a. O/O. The 8 & 9 are repunched at the bottom. The attribution is clinched as the remnant of an o is visible within the medium o. Heavy die clashing is seen at the right of lady liberty. This is the late die state as cracks are beginning to form on either side of the mint mark. CAC.
This is the key date to the o-mint barber series. There are several mint mark and date position variations known, but none are considered varieties or errors.
The 1900-o is another issue that was sent to the Phillipines in large quantities. It rivals the 95-o in scarcity and commands a premium to most price guides according to the Stella Coin News reference on Barber Dimes.
Ex: Simpson. Breen 3545, "Microscopic O." Howard Rounds Newcomb was one of the pioneer students of minute die varieties among late 19th and early 20th century coinage. He is credited with discovering the first "overmintmark," the 1900-O/CC Dollar. David Lawrence speculates this variety results from an employee using the mintmark punch designated for use on Quarters.
