The EJs are using it for stolen stuff too. I agree that two senses is probably best.

Sankoku claims this word is a colloquial abbreviation of 現物.
Sankoku and iwakoku have stolen goods (盗品), drugs (麻薬), etc.

I think this probably worked better as two senses

* gg5: 〔品物〕 《俗》 the stuff; the goods; the merchandise.
* wisdom: 〖品物〗goods; an article; 〖お金〗money; 【現金】cash; ｟俗｠dough.
* smk: 〔口頭〕〔現物・物件の意〕品物。現金。

The refs only have this as one colloquial sense. I'm also not seeing a "stolen" nuance being indicated.

Need a better reference. I suspect it's just a colloquial use of sense 2.
