1907 is the first year Dineros came with the initials "FG", standing for Francisco B. Gamarra. He took the reigns on January 16th, 1907 after the previous assayer, Jose Figueroa, died of tuberculosis. It is believed that all 1907 JF Dineros are counterfeit. Please see the 1907 JF page for further discussion. Gamarra served through the end of the Dinero series in 1916.
Starting in this year, and continuing through 1916, coins may be found with the initials FG over JF (and sometimes reportedly FG over other letterings). This is also the first year that a dot may be found under the "O" in DINO. The dots continued on some coins of each year through 1913. 1907 FG is very common in circulated and lower mint state grades. In Gem it becomes more difficult. Prooflike surfaces sometimes appear, especially on the reverse.
Krause lists the normal 1907 FG and 1907 FG/JF. Flatt adds a G/F. He notes that the 1907 FG/JF may come with a 7/7 in the date. The position of the period under the "O" in DINO may vary. Krause gives a price hit of $7.50 if the coin does not come with FG/JF, ignore this. The 1907 of any variety should all be at the same "common" date level. While I have seen a few pieces with a dot, most do not have one under the "O" in DINO, so the former may be considered very scarce. Although many examples have the FG/JF, many examples appear to be the normal "FG". I have also seen an example with a very large "7" in the date. As usual, the placement of the numerals in the date varies and I will not attempt to do an inventory for each die variety a la William Sheldon.
One at NGC in AU 58, four in MS 62 at NGC, one in 63 at NGC, two in 64 at NGC, and two at PCGS in 65 (one is FG/JF). I also know of a 1907 FG in MS 63 at ANACS which I briefly owned.
