Tests positive for silver any idea what it is?

My first inclination was an aluminum float for nets but it is isn't rounded like those are.
When I got it home it tested positive for some silver content. Can lead still test positive.
Would appreciate any ideas. It was found on a Lake Michigan beach

kinda confused...is it heavy?sometimes pewter has silver alloyed in it

Not super heavy and tough to tell cause there is water inside.

I have to say, it doesn't look high grade silver. Maybe a bit, was the test accurate?

It could be natural, unpolished silver.

The scratch test was positive. When I place the acid on the object itself it grew a little paler in color but didnt turn blue or the like.
By no means an expert on testing. Can pewter test positive?

Well it's NOT natural unpolished silver or even any sort of precious metal sliver or otherwise . And I don't know how it could be seeing it's in a manufactured shape of a cylinder (man-made) that has been crushed at some point . And it's not pewter mainly cause Pewter is a form of a pot metal that is very rigid and breaks very easy and corrodes visually . And seeing it's very light I'd guess that it some kind of Tin mixture or even a Aluminium mix . It just might be a small Aluminum can that was heated by a fire that beach goer's started that retained some of the continents . Maybe it was a candlestick holder weighted by fluid . IMHO , Woodstock

Candlestick holder interesting idea. Could aluminum show a postive test for silver?
