What is the value of vintage glass pedestal square candy dish?

Answer 1

Unless it is from a well known and collected artist or manufacturer, vintage (appearing) glass is still in production today and is often only worth a few dollars.

If there are manufacturing proof marks (to prove its age and origin) and/or dates on the piece, than the value will vary based on who created it, how old it is and how rare the design. It could be worth anywhere from $10 to $1000 depending on condition, rarity and origin.

Glass collectables are among the hardest collectables to appraise without physically seeing the piece because artisans continue to create these works by hand and high quality glass does not typically show age (unless damaged) so it becomes very difficult to determine the difference between something created 100 years ago and something created yesterday.

For this reason, even pieces from famous artists tend to fluctuate widely over time and their value is typically whatever someone is willing to pay based on its beauty and not necessarily its age.
