Found a Silver Cob

[HuntinDog]

I was extremely lucky and found a silver Cob.
It's only about the size of a US dime. 15mm x 20mm
If you want the full story, I posted it over on the XP Deus Forum. (Fantastic hunt and an Amazing Bucket Lister !! )
I know it's about wore out, but I'm hoping that someone can give me a idea of it's age or even which type it may be.

Thank for the look and any info you may lend.

The denomination can be estimated by weight.
If over 3.43 grams, it is not a 1R.
If over 1.72 grams, it's not a 1/2R.
