pinger Placer Mining, Slang 
n. See quote.
- 1958 Each pinch of dust was one dollar and it was pure, whereas in other gold everything above a pinger--that is, everything above something that pinged in the pan--was coarse gold, and a lot of this coarse gold had hidden quartz in it. So a thousand in dust was the real McCoy.
