Connoisseur England bone china plate dish floral small trinket vintage

Pretty little plate marked Connoisseur England fine bone china. I believe it may have been part of a child's tea set, but this is the only piece I have so I can't confirm. Floral design (pink cosmos?) with gold trim around the edge. I don't see any chips or cracks, but the gold is fairly worn. Measures about 4.5" across. Smoke- and pet-free home.
