shiner

Has she the shiners, d'ye think?

Fargo wasn't sure what difference it made if one gambler passed something to another, unless it was to be used in cheating, a shiner maybe. But nobody at that table would let a shiner pass.

Shiners are a big part of the wine business. […] Shiners are finished, bottled wines that don’t have a label or typically any other identifying feature until a vintner purchases them and then places a label on the bottles. […] They’re called shiners because they are unlabeled and have a “shiny” appearance.
