vintage unmarked bright yellow fiesta 12” chop plate

vintage unmarked yellow fiesta 12” chop plate. maybe a dinner plate or serving plate also. measures a little over 12”. unmarked. in great condition, except for 3 odd marks on the underside as seen in photos. i am unsure if the marks are factory flaws or wear from use. also, one pin prick sized skipped glaze mark on the plate’s surface (see last photo). likely a very early 1950’s or earlier piece.
