I think a remainder for this issue would have to carry a sheet number since these numbers were printed by machine, not written by hand like earlier black-and-white chartered notes. In fact, the 1892 Hamilton $20 in the Currency Collection has a sheet number, but it is overprinted SPECIMEN by the printer, Western Bank Note. Remainders and specimens are both printed like regular notes, but they were never issued to be redeemable for face value. Specimens used to be more collectible, but they have slid backwards in popularity while the market for issued notes has surged in the past 10+ years.
