While you probably won’t strike it rich with the first Minnesota quarter you find after reading this, there are many ways to improve your odds of finding a valuable Minnesota quarter.

Check your pocket change. This is probably the most convenient method for finding rare and valuable coins, because all you need to do is dive into your loose change to start hunting for state quarter errors. Of course, the downside to doing this is you’re pretty much limited to looking through only the coins you come into contact with during cash transactions and such. (“But there must be a better way…” Yes there is! Read on…)
Go through rolls of coins from your local bank. Many collectors search through bank rolls of coins to increase their odds of finding error coins, old coins, and other interesting items. The benefit of looking through rolls of coins from the bank is that you can search many coins all at once. Also, rolls of coins are generally obtainable for the face value of the coins within. So, if you want to look through rolls of quarters for the 2005 Minnesota quarter error, you need to pay just $10 for the roll, which is the face value of the 40 quarters that come in a standard quarter roll. Keep the ones you like and spend the rest!
Cherrypick 2005 U.S. Mint uncirculated sets. It’s possible you could find some of the 2005 Minnesota quarter errors by searching through 2005 uncirculated mint sets. An official modern US Mint uncirculated set contains one coin from each of the U.S. Mint facilities producing circulating coinage. In the case of the 2005 mint set, you’ll find (among other 2005 coinage) 2 Minnesota quarters — 1 each from the Philadelphia Mint and the Denver Mint.
