"Bakelite" was the first modern industrial plastic. Developed around 1910, it was used to make brightly colored everyday items like knife handles, salt shakers, buttons and jewelry.
From Sears to Saks, everyone sold Bakelite jewelry in the 1920s and '30s. Prices ranged from a few cents to a few dollars for pins made by Chanel and other designers.
By the 50s, Bakelite was no longer being made, and its jewelry languished in secondhand stores for pennies.
Today, Hyman says, "The prices have skyrocketed." A pin that sold for 79 cents now could be worth $300 to $500. An elaborate necklace with matching brooch and bracelet could bring up to $3,000.
The complexity of design and rarity of the pattern determine the value. Single color bangles can cost less than $20, but heavily carved or polka-dotted ones sell for hundreds.
For information on Bakelite, Hyman recommends experts Dee Battle, author of The Best of Bakelite (email address: email@example.com) and Arnold Reamer (email address: firstname.lastname@example.org.)
CBS News Saturday Morning viewer Elsie DeLucia from Titusville, New Jersey, brought in a bowl and cup set decorated with Disney cartoon characters and the alphabet, printed around the plate.
Viewer Gail Korneliusen, of Webster, New York, showed Hyman an Abraham Lincoln campaign pin with a photograph of Lincoln on it.
After conferring with experts in all three fields, Hyman concluded the pin is worth $1,500 to $2,000.
For more on the political buttons, Hyman recommends expert Ted Hake, author of the Encyclopedia of Political Buttons. His email address is email@example.com.
