It's an interesting piece and the information you've provided is great. I like the plow as well as the ship.The design seems to include some of Boulton's anti-counterfeiting measures employed on the cartwheel coins of 1797. Such pieces were struck using steam-powered coin presses, so I am presuming that this was similarly struck and was an early issue for the new steam technology. It provided a long run which would have been good for experimentation and proving the technique.I don't know which were the first tokens struck with steam, but this issue may have been close, if not the first.
Cool design, and I really like the cartwheel rim. Nice one, Stefanie!
