Hi, @Wahoogaz, how exciting to receive your new fiesta dishes!
I think my first purchase was 2011. As others here have mentioned, there are different backstamps.
My jumbo cups have the ink stamp marking, and it is marked Homer Laughlin China, lead free, Since 1871, USA.
A dinner plate also has an ink back stamp:
Homer Laughlin China Co, Fiesta, USA, and Lead Free. The ink backstamp on the dinner plate (and other pieces) also has the date code. One of my plates is marked ZZB which is the year and quarter of production. ZZ indicates 2011, and B means the 2nd quarter of the year.
I just took a look at one of my rice bowls, or also called footed bowl. This used to be a Dillard's exclusive, not sure about now. This has an impressed (not ink) backstamp, and is marked with a capital F, HLC, USA.
One of my small platters, impressed backstamp of HLC, fiesta, USA.
One of my individual pasta bowls, impressed backstamp in a circle design, fiesta, HLC USA.
This is probably more than you wanted to know! I think it is very interesting that HLC uses the date code on some of the pieces. It is valuable when identifying some of the colors.
Enjoy your Fiesta Ware!
