Professional appraisals are usually reserved for high-end items. You can learn how to value your Fiesta by learning more about each piece. The popular, colorful dinnerware was produced for many years. Introduced by Homer Laughlin in 1936, Fiestaware went through many changes over time including changes to colors, shapes, cup handles, and contour. Production ceased in 1973 but was revived in 1973.
You can learn about each piece by checking out the mark on the bottom as the mark style changed over the years as well. Learning colors and styles will help you date your items as well. You can learn all about Fiestaware by locating several books on the topic including:
"The Collector's Encyclopedia of Fiesta" by Bob Huxford and Sharon Huxford
" Warman's Fiesta: Identification and Price Guide" by Glen Victorey
"Fiesta: The Homer Laughlin China Company's Colorful Dinnerware" by Jeffrey B. Snyder
Remember that price guides do not reflect current values. You can find values at auction and sales sites online. How you choose to sell them depends on how much work you want to put into selling vs convenience. Online sales will take a bit of work. Selling to a dealer or through a consignment shop will not earn you as much as they will want a good percentage of the sales price.
