This has to be something of a  record for the amount paid for a single shot glass, even taking into account the fact that it's enameled:  

"This whiskey jigger measures 2 1/8" tall. The glass is thin and has highly embossed painted & glazed lettering, which is white with blue and pink highlights. It says, "OLD FISHERMAN". I have seen back bar bottles with similar embossing, but never a jigger. It is in excellent condition, no chips or cracks. Guaranteed original and old."   A lovely old glass from Freiberg & Kahn, Cincinnati

Junkmoney snatched it away from bluroc for a cool $383.77.  I may have to modify the "values" page on the basis for this one!  Congratulations to the new owner!
