What Are These Things For? (22 pics)
Old container made out of clay and coated in brass. It shows a image of church.
A: It's a decanter of some sort. One way to find out what's in it — open it up! If there is liquor inside there it doesn't get better with age. In my experience these "collectible" decanters aren't really very valuable. I found that out when I inherited a collectible Jack Daniel's decanter with a tax stamp on it from 1964. I contacted the Jack Daniels distillery directly and they told me that the decanter itself probably only had a nominal value of $10-20, and the whiskey inside doesn't age in the bottle or become more valuable. Only wine has the potential to get better with age after it is bottled.
