Buffalo Nickel With Rotated Die Error - Help Me Understand

Assuming that both pics were postrd sideways.... I think you have a little more significant rotation going on there.

It is easier (for me) to tell just how much rotation there is when the coin is set in a 2X2 with some staples. Then when you flip it over, the staples become the reference points.

The premium value depends upon the degree of rotation and the condition of the coin. Your coin is quite worn and I am uncertain about the rotation. The value of error coins seems to be all over the place so it's hard to guess the value with any real certainty.

I doubt it would have any added value in this condition.

A number of Buffalo dates illustrate rotated dies. As an avid collector of this series for many years, the most commonly seen years were 1913, 1914 and 1924-D. While some collectors may pay a premium for these, more so likely in higher grades it seems to me, this is by no means common practice. The rotation anomaly is one that all too often feigns rarity.

Carl ... I never gave thought to the Red Book not mentioning die rotations. What dates of Mercury dimes do you most commonly see with some die rotation? I seem to recall once seeing a 1925-D. I've seen many Buffalo nickels and Lincolns and other copper coins with 90 degree rotations, but not yet a Mercury dime with so near as much turn to it.

As to the Red Book starting on page 421 there is a decent list of different types of Mint Errors. The following pages have some examples too.
As to which Mercury dimes. I have approximately 3,000 of them. Now just finishing Album #12. Looking at the rear of the pages in those Albums, I'd guess approximately 25% of those Dimes have some Rotation. Some are minor, some drastic. Some are rotated to the Left, some to the Right. Usually most people don't notice such rotations since looking at a coin, flipping it over, it is difficult to notice if the rotation is correct. If you spend the time making sure all Obverses are straight up and down in an Album, then a turn of the page makes it more obvious.
And as I've said, some dealers have a difficult time selling such coins.
