If you have a question about a specific piece, you can ask a question on our Fiesta / HLC message forum.
The first place to look in order to verify whether an item is genuine is to flip it over and look on the underside. Most fine china is backstamped with the manufacturer's logo. The original Fiesta design and name were filed by Homer Laughlin China Company on March 20, 1937 (Patent No. 390-298). To the right are the four most common backstamps.
HLC could not mark some Fiesta items because of design considerations. Examples of items without backstamps include vintage juice tumblers, demitasse cups, teacups and salt and pepper shakers. Of the vintage line, some ashtrays, egg cups, sweets comports and onion soup bowls are marked, while others are not.
Once you become more aware of the design and color, recognizing Fiesta becomes easier. The key pattern to recognize on a piece of Fiesta is a band of concentric rings graduating in width. In its design, the rings closest to the rim are more widely spaced.
One of the Post 86 Fiesta backstamps contains a useful three letter date code. Note a series of three small letters in the backstamp itself. This is HLC's date coding system which it has used since the 1960's. The letters AA indicate , BB indicates , CC indicates , and so on.
The last letter indicates what quarter of the year an item was made. Therefore, A represents the first quarter, followed by B, C and D. Therefore a backstamp with the letters KKA indicates that the item was made in January, February or March of 1996. Note that the backstamp only indicates when the item was formed. It does not take into account the additional time to completion. Therefore date coding should only be used as an approximation. However HLC did not utilize this stamp until six years into Post 86 production, nor has it been applied consistently to all the Post 86 pieces.
In , Homer Laughlin added a small raised H to the undersides of all Fiesta made from the original molds. This includes, for example, the bud vase, candlestick holders and disc pitchers. However note this convention was added only during the midpoint of the post-86 pearl gray production.

Flip over a Fiesta dish, cup or trivet, and you can determine that piece's production date down to the quarter of the year, if it has the three letter code backstamp.
