Lead Something Or Other

Coins in lead (Latin: plumbum) do exist, but they are scarce, because lead is a poor metal for the manufacture of coins. It is soft and subject to corrosion, and for those reasons, few lead coins have survived.

I have two:
South India Ishvakanids. 2 grammes. date 230 to 310 AD Obv.: Ujjain symbol, Rev.: elephant facing left.

Khmer kindom of Angkor floral 3 units. 15 grammes. circa 1450 AD. same pattern on Obv. and Rev.

Because there is not much numismatic demand for such pieces, they are not highly valuable, despite the fact that they are quite scarce.

seals of this type often begin their lives plain:
the obverse & reverse images are often added by the crimping tool that closes the seal onto the two ends of string (or whatever) that the seal is being used to protect.
OzPost used them a few years ago: don't know about mine.
My electricity meter has one.

I agree that it's a lead seal and probably eastern European in origin

Wow, you guys are good. I would have completely believed it to be a coin if I found it in a display case at a flea market described as an ancient. OK, maybe it would have taken an unscrupulous vendor too, but still thanks for sharing. I remember on some antique show when two seasoned antique experts got bamboozled by a flimflam artist. It happens to us all.
