A customer just brought in four old (1700s?) Great Britain assayer's medals. Can anyone tell me about these. Seem pretty interesting. Pete
You say coinweights. Are these a standard weight for a certain coin? Like used to tell if coin is real? Or used to weigh blanks/planchettes with?
Yes to the first question. Maybe, sometimes, to the second as well. (?) https://en.m.wikipedia.org/wiki/Coin_weights (Side note: the glass weight shown in that article is neat. I did not know they existed.)
They were used to check the correct weight of mainly gold and silver coins on a balance scale, to check if they were genuine. Here are some pictured on Tony Clayton's site, who is a member of CT. http://www.coins-of-the-uk.co.uk/pics/weights/index.html
