Antique Amber glass?

I am trying to find information on some amber glass items I recently found. The lady I got the glass from said her daughter bought it for her 40 years ago. I have a decanter set with decanter, cap plug, round tray, and eight goblets. I also have two candlestick holders and a basket with handle. All of these items match with similar markings in the glass. The point where the basket handles meet the sides of the basket has the letters “JD” imprinted into the amber glass.
