Antique Fiestaware is more than just colorful pottery. Here's what it's worth

When you look at Fiesta or Fiestaware dishware, it looks so modern. It’s hard to believe it has been around for more than three-quarters of a century. The U.S.-made dishware features Art Deco styling and is favored by collectors for its bright colors and craftsmanship.
The Homer Laughlin China Company began manufacturing the dinnerware in 1936 according to Wikipedia. The dishes owe their “look” to Frederick Hurten Rhead, an art director for Homer Laughlin China. Fiestaware was the first mass-produced solid colored dinnerware available in the U.S. When Fiestaware was introduced, according to Wikipedia, most people still used Victorian Era inspired dishes. These dishes were matched sets that featured the same decals and designs.
Fiestaware shook things up when it came to market because the dishes were available in many colors and also sold by the piece as well as in sets, according to Wikipedia. This selling innovation allowed people to mix and match items.
At the height of production, the Fiesta line included 64 different pieces. World War II and subsequent austerity led to the decline of production, according to Wikipedia. The line was put on hold from 1973 to 1985. When it returned to the market in 1986, some pieces sported a new look and a more durable composition.
Vintage Fiestaware is prized by collectors. According to recent auctions on eBay, a single piece of Fiestaware can go for about $20. Happy Heidi, a site dedicated to Fiestaware lists specific pieces and their value.
Example prices on the site include $85-$295 for a Fiesta ashtray, $800-$8000 for a covered onion soup bowl and $85-$4000 for a cream soup bowl. The valuations for more common pieces are lower, but rare pieces command a higher price. Happy Heidi estimates are for pieces in excellent, flawless condition.
