Pearly Dots, Westmoreland   Updated 5/23/2007
I consider all pieces with smooth dots to be Westmoreland's Pearly Dots pattern. Those with stippled dots are Fenton's Coin Dot pattern. I say this without 100 percent conviction, however, because of the crimped bowl on the right. The candy ribbon edge is a fairly common Fenton edge though the dots are unstippled. Did Fenton make both a stippled and unstippled version? Frankly, I don't know. In any event, the origin of manufacture makes little difference in the value of the piece.

Compotes are usually taller and less flared than this great blue opal example (courtesy of Dick and Sherry Betker). They are sometimes misidentified as Fenton's Inverted Coin Dot. Rosebowls are found in a variety of sizes and the degree they are cupped in varies quite a lot too.
