Russia wire money - Ivan IV or Michael I? [resuelto]

Looks silver. 0.4g 9mm x 13mm that letters are legible but I cant find a match.

Ivan IV wire money are at 0.68gram or 0.34 gram. It is not his kopek or denga just based on weight.

Those letters do not tell ruler name. Only Czar and Grand Duke part.

If your weights can't do hundredths of the gram, Michail would be between 0.48 and 0.45 gram. Early Peter/Ivan V wire money are around 0.40 gram.

Ah. Thank you kindly. When I did the search of the weight and size Mikhail and Ivan IV were the most that showed. so that was my guess it was either one.

Above, are both a Denga and a Kopek of Ivan IV, with info on available books, one link broken until I fix it.

I'd need an email to send you a resource or two, or you can check out this site, below.

This is a hard case, but this is a coin of  Alexey Mikhailovich. 

I think this type: N#242505

Thank you kindly.
