Coin and Paper Money Collecting/Tennessee Quarter


Hi Ronald,
I just wanted to inquire. My room mate just pointed out to me |I may have a misprinted 2002 Tennessee quarter but thought I should probably ask you as we live in Canada. She pointed out the head side of the quarter is completely upside down as to the other side of the coin with the guitars and trumpet. Is that normal or could this be a collectors interest at all ? I hope my description made sense.

I look forward to hearing back from you.

Kind Regards,



I think you have a normal coin.

From: "The U.S. uses what's called "coin rotation", where the front and back sides of a coin are oriented 180 degrees opposite. Take a look at two of your two quarters - if you hold your dollar so Washington's head is pointing the right direction and flip it side to side like a book page, the design on the back will be upside down." Are your coins like this? If so, they are normal, and worth a quarter.

Many more countries use "medal rotation", named because both sides point the same direction like a medal that's hung from a chain or lanyard. Examples are coins from Canada, the UK, and the EU. Beginning collectors often make the mistake of assuming a coin has a 180 degree rotation when in fact it's simply made according to the issuing country's standard practice.

Read more:

From: "Rotated die coins usually occur in two different ways, the first being the mint employee installs the die incorrectly so the obverse and reverse do not line up properly when the coin is struck and the second is when the die becomes loose and then moves a little bit as each new coin is struck." If it is a real 180 degree rotated die coin, it could be worth up to $100 or more to an interested collector, depending on the condition and market.

If it's altered, it should make a dull sound when dropped compared to a normal dollar. This would happen if someone took two dollars, cut them in half and glued them back together with the reverse rotated to make the "error". Altered coins have no added numismatic value. Can you weigh your coin? A clad U.S. quarter weighs 5.670 g, 24.26 mm (0.955 in) in diameter, and 1.75 mm (0.069 in) thick. You should be able to see where two coins were joined together by using a magnifier. It would be along the edge or on the inside of the rim.

You may want to check Ebay listings under US coins in the error category to see what these errors are going for. You may also want to check out these links on error coin values:

If you live close to a local shop, they should offer an opinion as to it's value and if it is authentic at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. Here's a link to find one in your area:
