This week a Newman Portal user searched for "Tristram Coffin." Was this a trade token for a 19th century undertaker? No, and that would be a bad guess. An appearance in the Stack's Bowers March, 2016 Baltimore saleidentifies the Tristram Coffin medal as Betts-533, and from there Betts' American Colonial History Illustrated by Contemporary Medals gives further information, as supplied by editors Lyman H. Low and William T. R.Marvin:

The Stack's Bowers cataloger notes these medals were actually produced in 1827 by Thomas Halliday in England, making this one of the "youngest" pieces documented in Betts 1894 reference.
