Here is a visual comparison between pool balls. The faded 12 ball is from what I would assume the original set that came with the Brunswick Hawthorn pool table. I'm supposing that was manufactured in the '80s. The shiny brand new looking 12 ball is a newly purchased set from Dynasphere, specifically the Bronze model. The strange aspect of these two pool balls is that the new Dynasphere has a diameter of .249", and the old Brunswick set has a diameter of .229" . To me something sounds fishy, as I thought diameters of standard pool ball sets are 2 1/4 inches? I measured these with my calipers, which are spot on as far as measurements are concerned. This is the same device I use to measure when I reload ammunition and want to be very precise.
