This is the only example of this year known with this finish. The others were struck with the "Roman Finish".
It is possible that this was deliberately struck for a collector or as an experimental piece for this finish which was ultimately rejected.
It is ex Dibello lot 1004, Auction 81 lot 1868, Trompeter, Goldberg 2/06, B/M 2009 ANA.
