NOTE- My eBay name is "mr.goodpic" because I am a semi-pro digital photographer and am finishing up editing my booklet on how to take pro quality pics of eBay items with little effort; learn the one simple secret! The better your pics, the more you will sell, as great pics give buyers confidence in you as a seller. I will have this booklet for sale in digital format shortly; if you are interested let me know and I will contact you when the booklet is listed on eBay, or just check back and see if I have it for sale yet, I'm doing the final editing now. I will sell it for $5/copy.

I searched ebay, no amber color glass furniture coasters by Dominion, only a few listings in clear/no color Dominion coasters. There were several listings of amber glass furniture coasters by Hazel Atlas, in fact the great majority of vintage glass furniture coasters are Hazel Atlas on ebay. Dominion Glass Company is/was in Montreal Canada, don't know if they are still in business?

Both coasters are identical, no chips or cracks, crystal clear beautiful rich amber color glass. Both coasters measure 2 7/8" outer edge  base diameter, 2" inner edge base diameter, 3/4" tall. Very minimal wear on the inner bottoms, and both coasters have a fine thick ring of base-ware on the outside bottom near the edge, see close-up, does not detract. I am guessing these coasters could be oldest 1920s, newest 1950s. Both coasters have the embossed horizontal Diamond D and MADE IN CANADA,  see pics. Please ask any questions.
