I have a group of five unusual pewter thalers that I purchased in Europe a few years ago. I am pretty sure these are 18th-19th century restrikes, perhaps a type-set given the metal they are struck on, pewter rather than silver, and the fact the coin inserts are hand written in calligraphy on paper that clearly shows signs of age. You can see the paper has a faint lighter area where it was in contact with the coin. Each coin is approx 40mm in diameter and weighs about 22 grams. The coins have a density of 7.6 g/cc indicating they are pewter. Has anyone seen anything like these before? Any help identifying the age, value, and what these would have been used for would be very appreciated.
