I'm not sure... trying to figure that out (Edit) just found a protractor and the 71 looks to be 20 degrees.
Does the mint list it anywhere? because The Lincoln Cent Resource says 8 degrees variance and I found a page online for quarters that says 5 degrees variance.
Allow me to correct myself... mint variance is 8 degrees, it has to be more than 15 degrees to be considered an error worth keeping. Sorry about me getting my facts mixed up. I'm dealing with a really bad hangover today.
These cent coins used to fool me quite a bit until I found a better way to check them out and I have learned they are not worth keeping unless they are rotated by at least 80% the best way to check the rotation of the cent coins is to level the bottom of the monticello building in the coin holder then examine where the obverse ot the coin is setting. Most folks including me can never seem to know whether the obverse side of the cent is sitting on correct level or not.Try this and you will soon see that the coins you once thought were rotated are not rotated much at all. It is common for our cent coins to be rotated bt as much a 10%
If you look at my pic's and notice the line on the 2x2 (obverse) you see that the top of liberty is the center of the coin so just line up liberty so that it is flat that's the correct orientation.
Probably an obvious answer that I'm over thinking, or right on, but is mint variance basically the allowable degree of rotation that can be exhibited on coins, and therefore not really an error? That's what it sounds like. BTW I think you meant Lincoln Memorial.
"The U.S. Mint allows for an error margin of less than 8 degrees. Rotated die errors are usually not collectible unless they are at least 15 degrees. Rotated die errors are most valuable after 90 degrees with 180 degrees being the most valuable"-the Lincoln cent resource
