While on the subject of George Washington, regarding Glenn A. Mooney's pioneering work on the Washington Before Boston medal, John W. Adams wrote:

I am happy that my article about the Die Varieties of the Washington Before Boston medal has sent people back to their collections to look at the medals. I hope that more people will report their findings. A die emission sequence can only be theorized and verified by looking at the medals themselves.

John Adams' recent report in the Esylum newsletter of October 7, 2012 that there are examples of F1 "that are from a later obverse die state than most of the F-2's and F-2.1's" would certainly make sense and would be consistent with my study. The error reverse, F2 and the corrected error reverse, F2.1 did not experience much use. There are only 4 known error reverse, F2 (Scarinci, Menchell, Adams have 3 of the 4) and no more than 8 or 10 corrected error, F2.1 (Menchell & Adams account for 2 of them). The corrected error reverses, F2.1, that I have seen, all show die failure. It is certainly possible that the Paris Mint reverted back to using the original broken reverse after the failure.

If John Adams' observations are correct then collectors who own original F1 Washington Before Boston Medals need to carefully examine them. Early die states would be more desirable because they are more likely to have been struck closer to the time of George Washington's gold presentation medal. The gold presentation medal is the earliest state of the original obverse die.
