How do I spot reproduction Depression glass?

Many popular patterns of Depression-era glass have been reproduced, sometimes in colors that were never made originally. Reproductions may have a slightly different weight, a different color tone, blurrier or less detailed patterns, or mold seams in different places than the originals.

Collectors who specialize in Depression glass often rely on small details in the pattern, such as the shape of a design element or the way a line meets the edge. Reference books and collector club resources compare originals and reproductions side by side, which is one of the best ways to learn.

When buying, ask the seller whether they guarantee age, and buy expensive pieces from dealers who know the field. If you have a collection to sell, an auction company or dealer who handles glass regularly can help sort out originals from reproductions so you price them correctly.
