I don't know anything about coins but came across this 1841 Large Cent. The reverse is approximately 90 degrees off from where it should be. I put a piece of white tape that wraps around from the front to the back so you can see the offset. What is this called? Is it rare? Does it have any value? Thanks for any info.
Welcome to CT, bgkahuna! I don't know the value of your coin, but putting the tape on it most probably reduced its value. The glue on the tape damages the coin.
It is called a rotated die. In my experience rotated dies are not uncommon from US coinage in the mid-19th century. This is apparently a substantial rotation, so in my estimation it adds a little bit of value to the coin. There are people on this forum who are much more knowledgeable than I who will most certainly weigh in on this.
Welcome to the neighborhood! Yes, you should remove the tape if you haven't already. One of the easiest ways to show the degree of rotation is to mount the coin in a 2x2 carboard holder that has the mylar windows front and back. With the obverse mounted in an upright position (perpendicular to one of the sides) all you need to do is turn it over in a north-south (top-bottom) direction. Chris
degrees? i love rotated coins! i don't get the tape thing. could you go to www.rotateddies.com and then click on 'Measuring coins', and then figure out how many degrees the coin is rotated? thanks!
