I inherited this plate from my grandma. I don't really know anything about it. The stamp on the back says La Francaise and then under that BEMI or DEMI maybe and then under than an 8 letter word ending in -eous. I can't make out the first letters. At the very bottom of the stamp is the letter A and the number 4 and there is a big gold 2 in the middle of the bottom. Anyone know what the seal on the back means or what it might be worth? Thanks!
