CTX 3030 River Hammered
Decided the weather was just right for some shallow water hunting. I was travelling to one location, and changed my mind.... ending up on a river crossing that I had previously worked with a CZ20 and then an Excalibur& Excalibur II.
I had found some nice Roman coins over the years, and also a lot of 17th to 19th century coins.... But I always knew there would be some other stuff a bit deeper in the hard pack.
I worked an area where find should be deeper, and the first target looked promising, a lead disc with patterns.... could it be early Medieval?
Next signal was a James II tin farthing (with a square copper plug).
I got a hammered and not a run of the mill one![split]
The tin coin is dated 1685 on the edge.... Just seen the prices in Spinks
I've looked through all my books... I'm not even sure it's a penny now... it only weighs .5gr (18mm), so it could be a halfpenny. I think it's likely to be a Viking imitation.
Various chemical methods to remove each deposit. Fist a scale remover to remove calcium river deposit.... then a pickle solution to remove the verdigris... then soda crystals and foil to loosen the silver sulphides.
