Here are new and old examples of demitasse cups. While the handles are identical, their bodies are different.

The red cup on the left is older -- it has a foot as well as interior rings. The turquoise cup is the new version -- no foot and no interior rings. Also, new demitasse cups have an in-the-mold marking.

Stick Handled	Regular	Ironstone
Above are three versions of Fiesta creamers. The stick handle creamer was original, but was replaced by the regular or ring handle creamer early during production. The Ironstone creamer is a restyled version with a partial ring or "C" handle. This shape is used in the new Fiesta line.
