One of my white whales finally captured?
There are a number of key coins in the Mexico Mint Portrait series (1772-1821), especially if you get into varieties. Two of the most difficult and expensive coins to find are the 1778 with assayer initials FM and 1783 with assayer initials FM (vs FF). Only a handful of each type are known to exist. Yonaka, surprisingly, only calls it an R2 with 5 examples each documented. I guess from an absolute scarcity point of view he's correct, especially taking all other varieties into consideration with some varieties only having 1 or 2 examples documented.
To give you an idea of a price, here's an example in XF+ that sold at Aureo in 2014 for €12,000
Fast forward to my most recent NGC order. I knew the coin was nice with a touch of luster and some peripheral color not obvious in NGC scans, but i didn't realize it was this nice:
So nice, in fact, that it's able to change assayer initials on demand
Yes, it's a "mechanical error". And @coinkat I confirmed - it was submitted with the proper description on the form.
Thought the forum could use a chuckle this monday morning.
