Swamperbob and I briefly discussed a 1833 GoJM 8 Reales specimen (assayer JM is a listed variety, rare and much more expensive as compared to the common MJ assayer for that year) a number of years back:http://goccf.com/t/143938
One popped up recently on eBay. In looking at that piece, other auction archive examples, and going back to that thread from years ago... I think that 1833 GoJM issue might, in its entirety, be a contemporary counterfeit - or at least a "back room of the mint" debased issue using official punches.
Long story short - and we can discuss this in more detail - every example of what is called/sold as a "genuine" 1833 GoJM 8R that I see is from the same die pairing... and most/all of the more worn examples appear to have revealed themselves to be debased examples.
Just a quick few points:
-- All of these 1833 GoJM examples purported to be "regal", genuine pieces - again, seemingly all from the same die pairing - are NOT a match to the one 1833 GoJM 8R shown in Riddell
-- These "genuine" 1833 GoJM pieces DO, however - as I think Bob alluded to in the old thread linked above - appear to be a perfect reverse die match to Riddell 304, a rather commonly seen 1833 GoMJ debased issue.
Bob, would love to hear your observations on this...Examples of the 1833 GoJM "genuine" type:Examples of Riddell 304, 1833 GoMJ, which look to be a reverse die match to GoJM shown above:
