Staffordshire Elizabethan Forget me not pattern used only 3 times. Not chipped or marked in any way.

hi if it is just the up and saucer the I would estimate 15 - 20 usd, I am not an expert but do collect
if you would like to get it valued take it to an auctioneer, it is vintage not antique also remember they have their costs if they auction this for you, and it also depends in wich country you live
hope this helps
thanks kathy
