were can you get that info at?i thought that rotation amount affects worth meaning the more rotated the more it is worth,but a small rotation is still an error.
Actually, that is incorrect...it clearly states that the mint error margin is less than 8 degrees. It states that rotation errors aren't considered COLLECTABLE until they reach 15 degrees or more. So a die rotated 9 degrees is considered an error...it just won't command a premium. Knowing the sales of rotated dies, I can say that they generally don't command a significant premium until about 90 degrees rotated on normal coinage (older coinage, such as coins struck in the 1800s, may command stronger premiums because of their age)
This page is a bit perplexing http://www.lincolncentresource.com/Errors/RotatedDies.html After the narrative there is a list of dates/mm's They don't seem to be links, and there is no discussion of what the list is. Any one have the inside skinny on this?
It's just a list of some of the dates and mints known with rotated dies (probably those with some of the largest rotations) and how rotated they are.
Something to mention. For those that are really into rotated die errors....older coins with rotated dies, like half cents, large cents and indian cents are more common than modern day rotated die coins. It has to do with how they keyed (or didn't) the dies into the coining presses. Earlier series of coins were not keyed well in the presses and if they became loose, a die could rotate fairly easily. Modern coins have dies with keys (raised areas) that essentially lock the die in place when the die is installed in the coining press. In the overall scheme of things, a rotated die on a Statehood quarter, for example could be much more rare as a type coin than a rotated die error on an indian head cent. Consequently, older rotated die coins can be found for lesser premiums than you might have to pay for a modern rotated die error. As an example, in my years as a collector, I've seen dozens of Indian head cents that exhibit degrees of rotated dies. I have seen only one genuine rotated die on a Kennedy half.
