Round flat lead coin/ game piece?

[iukams]

Found this at a old house built back in the mid 30s. Its flat and round made of lead and looks to be hammered. Any ideas?

It could be a bag/bail seal, but we need to see a pic of the back to ID it. Breezie

The back looks just like the front, no markings.

Is that a "2" located @ 12 o'clock, north of center? Breezie

hand made fishing line weight. You could easily tie it to the line using the slot and them lightly tap the slot close for a semi-perminate attachment.
