What are some tips on determining the value of old decanters?

Determine the value of an old decanter by its age, condition, material and design. Any historic or cultural significance adds to the value of the decanter.

Older vintage decanters in good condition can be valued more highly than the newer ones. The more ornate its design, the higher its value. Silver or gold decanters are clearly more expensive than those made of glass; however, you should also consider the thickness of the glass and the carat of the gold used. Check the item to make sure it is sound. Cracks and significant scratches in a glass decanter reduce its utility and its value.
