There's a new 3rd Party Grader on the block. BAC

What fresh hell is this, then? 65.80? Is this a simple average? Weighted by denomination? By surface area? What if one or two of the denominations are condition rarities? If one had a scratch, would it be "DETAILS/10"?

The OSV / Anacs sets have been around for about a decade now (started in 2016). I have never seen a details example nor a set with a condition rarity. For the condition rarities, I imagine someone would send the coin to NGC or PCGS. For details, I'm not sure-maybe it is rejected since you can't get to the composite grade with a details coin.

What is a “Composite Grade”?
The composite grade is not simply an average of the individual grades. This trademarked formula includes factors such as a Red cent being more valuable than a Brown cent, a Full Bell Line half being more valuable than a non Full Bell Line example. Additionally, the half dollar in any given year is typically more valuable than the cent or dime. Thus it is weighted heavier in the formula.

 

Shades of "market grading".

But I do see from the FAQ that it's possible to look up the individual coin grades on the ANACS site. So at least there's that.
