Indian1,the only attempt I have seen online to determine which was rarer was by Ken Potter. Actually,the article was on
WAM's and his comment,in passing,was that the 99 appeared to be rarest with the 98 next rarest and the 2000 the most common. I believe this is the info that keeps getting repeated but Ken was only making an observation based on the number of examples on
ebay and nothing more than that. His statement was not meant to be a definitive statement,it was simply an observation. I think the 98 is the most common with the 2000 next and 99 is rarest by far of the three. I don't believe we will ever know, but from what I see reported on this forum,and considering the amount of coin"processed"by folks here,a count(actually an "accurate count"not a competitive count)of what everyone has found might give us a better idea of rarity.I don't think there is a way to do a definitive assessment of populations.
