How Do American Tpd Coins Cross With ICCS? (And Visversa)

Hello,

I've noticed what appear some surprising trends in what crosses between ICCS and American TPGs. Canadian large cents in ANACS holders (and ANACS is not very respected in the US, or at least their grades are not) seem cross very well at ICCS.

I read a post recently about NGC PL coins (from the 1950s) crossing well at ICCS. I found several cross graded 1950s PL coins and usually NGC was one grade HARDER on these than ICCS.

Anyone else see crossing trends?

It is not really surprising that there may be some because different specialists who revived different type coins probably are quite different in their standards and a given service might be expected to be easier or harder (compared to ICCS or any other individual) depending on the grader(s).
