Salt shaker lid....silver or junk?

[MT_VertCaver]

I found this salt shaker lid tonight. Underground (6 inches deep) the TID bounced between 38 and 40.

Once I dug it out, it air tests a very solid 38.

Could it be silver? Or is it pot metal or tin or ???

I have been told if you rub it on a piece of white paper and it leaves a light pencil color line it is probably pewter. Look up the frenches mustart test also.
