Theodore Haviland Limoges - blue peony teacup and saucer

Description

Saucer has an indentation on its face in the actual ceramic, from somewhere in its production. Bottom has "TH" embossed into ceramic, as does the cup, but it's not as pronounced on the cup. At least it looks like it's an embossing to me. I tried to photograph these.
I'm unable to find a pattern name. These blue flowers look like peonies to me but I'm unable to find a match anywhere online. Does this mean I have a RARE set? Let the bidding begin!
