I was left tons of these antique/vintage Glass vases all different colors/patterns/styles/shapes & etc. I have no idea their worth. I have been reading up on it to gain some knowledge but I need assistance. Some items do have the pontil circle mark at the bottom/ along with the bubbles that is mentioned on determining age and some items do not at all! I have really tall and big ones and heavy thick glass and some that are small and thin glass
