So I have a #66 aristocrat in my den and a #58 on its way to me now and it got me thinking about the 1953 coronation set. I'm looking for any good info on it.

The only problem is that they put out a 70gram model and a 53 gram model that year and I'm not sure which it is or how to find it. Not sure if they are titled differently or which one is the right one. Here's a pic of the 66 And the 58
