Fenton amberina small hobnail vases

I still have trouble passing up Fenton Art Glass pieces and was trapped by a pair of small amberina hobnail vases for $.99 each. Someone was using these as votive candle holders and both had rust inside on the bottoms from the metal bracket in the candles. I've gotten most of it out but still working on it. I've never seen these in amberina before. Still frequenting thrift shops as I am in the process of replacing any implements for food use, even for my cats, that is "Made in China". I don't trust their food safety worthiness, any longer. Lots of good quality American made stuff in thrift shops. My cats are currently supping from some nice Italian made dinnerware.
