EAC Grading - a general rule of thumb?

RTS

Appreciating that it would not be scientific but does there exist any rule of thumb used to establish a linear relationship between a standard grade (PCGS etc.) and EAC grade - I would imagine in the real world the relationship would be governed by sundry factors versus a simple standard grade*X + A = EAC but am curious if anyone uses such a ballpark estimation when viewing large cents - comments very much welcomed - thank you.

In general the EAC grade is one adjective grade below the commercial or slab grade. In other words an EAC Fine-12 quite often qualifies as an EAC VF-20. This is the general rule for the circualted grades.

This only a very general rule. EAC grading does not slam coins that have had things done to them with body bags. The coins get graded, but there are deductions, called net grading for the type of work that has been done.

When it comes to Mint State grades, EAC gets a lot tougher. There are many early copper coins with slab grades as high as MS-64 that would get no more than an AU grade from a strict EAC grader. An "EAC Unc." has full mint luster and no rub. That can not be said for some of the slabbed Mint State coins that I've seen.

I agree with Bill Jones on his statement about Mint State grades.

In lower grades, the deviation between EAC and, say PCGS, is smaller. However, as a copper aproaches the Ex. Fine and Abt. Unc. grades, this deviation grows considerably. Some coppers which are EAC graded Extremely Fine or About Uncirculated could easily slab as Uncirculated. I've seen many large cents with plenty of rub slabbed as Unc.

I'll see if I can expand upon this later.

If it has rub, it ain't "new" or MS!!
