How in the name of Eric P. Newman is it possible for different sets to have the same ranking?
I am referring to my 1940 year set (which has been the #1 set in the registry for six out of the last seven years) and Coinbuf's 1940 set. My set has the #1 ranking for 2020, and so does his.
Yesterday, my set was in the #1 position, and now it is #2.
How is this at all possible?
