1958 Lincoln Memorial Cent Rotation Errors

Thank you for the quick response. It is greatly appreciated. But how do you determine the percentage? Is there a chart that can be used?

45-90 degrees

the whole mirror thing threw me off I for a minute thought you had two coins there lol

Easiest thing to do is get some 2X2's one for each size coin. Draw a line from the center of each side across the hole to the center of the opposite side. Do the same thing from each corner to the opposite corner. This puts lines around the hole at 0, 45, 90, 135, 180, 225, 270, and 315 degrees. Put another mark by the hole half way between each of the original eight marks. You now have marks all the way around the hole each roughly 22 degrees apart. If you want you can put marks halfway between each of these as well and you will have marks every 11 degrees apart. Do the same thing to the other side of the 2X2. Then do the same thing to each size of 2X2.

Now whenever you want to determine th amount of rotation of a coin you select the proper size 2X2, place the coin in the 2X2 so that when you close it the top and bottom of the obv are lined up with one of the lines going from one side to the other. Holding it closed turn it over and you should be able to read pretty directly what the rotation is.

This gives you direct die rotation measuring devices for most any size coin at a cost of about 21 to 35 cents. If you lose or damage one you can make a new one for under a nickel.

No a flip is different. A flip is the two pocket vinyl holders where you put the coin in one pocket and a 2X2 card in the other with the identification of the coin on it. They are called flips because you "flip" the coin back to see what is on the card, or you "flip" the card side out of the way to see the back of the coin.
