Paper labels were replaced around 2000 step-by-step (depending on design) with clear plastic labels - so your dish will be pre-2000.
I don't think it is a "Mini Mare" - Mare is not that much undulated, has a different glass structure, and I don't think it would look any good with only 16 cm (6.25") dia.
"Schale/Teller mit Wellenrand
" looks more like it: an old design - already in the 1995 catalogue (the oldest one I have). But the smallest I can find in catalogues is 21 cm dia.
The Wellenrand designs also have some surface structure - your dish looks rather smooth. The (discontinued) "Seerose" design was smooth - see attached image from the 1995 catalogue - but, again, the smallest size quoted is 23 cm dia. Whether a smaller one was available pre 1995 I wouldn't know.
