I was recently rereading my copy of Rob Turners Dies & Diadems and know the last obverse dies for 1888 were made from sub-punch O2S.
The same O2S sub punch would make all 1891 obverse 2 dies and some more dies for the 1892 coinage.
I'm pumped because I picked this up recently, these are really not that plentiful.
I've been tracking the O2S Obverse for some time and have come to the conclusion there were only three O2S dies used in 1888.
Considering there were 4 million 1888's minted and the number of dies that would have been required only three dies is quite low.
Mr Turner has also estimated they minted about 6% of the 4 million coins.
This is one of the possible three 1888's minted by an O2S Die.
The distinguishing features that set the O2S apart from most 1888's in the top serif on the "D" in "CANADA" missing and the bottom stand on the left leg of the "N" in REGINA" missing.
I just thought I'd bring this up and see if anyone else is studying Rob Turners Works?
Cheers, Bill.
