As a series the British (mainly Scottish) Tradesman Countermarked Dollars are considered very rare to scarce with only a few types generally readily available for collectors. The recall of these countermarked dollars by their issuers seems to have been generally very effective and relatively few pieces of most types have survived. I have often wondered how many issues have no surviving examples recorded. There may be a clue as to enterprises that could well have issued countermarked dollars and examination of some of the countermarked halfpenny coins is a good starting point.
