This week a Newman Portal user searched for "Rothsay Cotton." I thought this might be a 19th century American cotton producer in the south, which turned out to a bad guess, especially since tradetokens were more common in the north. Rothsay Cotton is in fact a UK countermark, and the first related document identified by Newman Portal is an index of the Virgil Brand ledgers prepared by UKresearcher Eric Hodge. This index notes a number of related issues in the Brand collection, either from Rothsay Cotton Works or Rothsay Mills, which are listed in secondary ledger #12 (p. 148).

A recent (May 2016) issue of the NI Bulletin, published by Numismatics International, contains an article on the subject by Hodge, which states "...Another Scottish cotton concern thatissued countermarked dollars was the Rothsay Cotton Works. Rothsay lies about forty miles southwest of Glasgow at the head of a bay on the Island of Bute. An English engineer, James Kenyon ofSheffield, moved to Scotland to evade Richard Arkwright's patent on his water frame. In 1779 he not only opened his new mill but employed ex. Arkwright employees that he had lured away with him....."The variety depicted here, 4/6 (of a crown), is scarce, with 48 examples known.
