Almost certainly. There are different companies that "colorize" the state quarters and sell them at inflated prices as "collectibles", so there are different patterns.
The U.S. Mint doesn't make "colorized" coins, so anything you find in change with added colors is considered to be an altered coin with no extra numismatic value.
State quarters found in change are only worth face value.
We found the 2007 colored state quarter sets (with white background) on the internet and were able to purchase 2 sets. We have not been able to locate the 2008 set. Do a goolge search, maybe check Ebay for 2007. You can purchase them from 50 State Quarters web site but they are upgrading their site at the moment. They sell the colorized quarters with the white background.
1970 quarters are still found in circulation and are not only face value.
All of the "State Quarters" found in change are only face value.
There are 25 pennies found in one quarter. There are 4 quarters in one dollar. There are 10 dimes in one dollar.
These are generally worth $5 to $10
It's a tendon found on the hind quarters that controls the muscle movements of that hind quarter.
It depends on whether you want the mass of a circulated or uncirculated quarter and the accuracy and precision you desire. A good balance (found in many science laboratories) would give you the mass of an uncirculated quarter probably with all the accuracy you need. It would do the same for a circulated quarter but it would be accurate for only that quarter. To get the average for circulated quarters you could mass a roll of quarters on a good balance or spring scale (postal scale. grocery scale, etc.) and divide by the number of quarters in the roll. For highest accuracy you should remove the quarters from their container.
The mint mark on a quarter is typically located on the reverse side, just to the right of the eagle or design element, depending on the specific quarter series. For example, on the state quarters, the mint mark can be found near the bottom, often between the engraving and the edge of the coin. In some older quarters, such as the Washington quarters, the mint mark may also appear above the "D" in "Dollar."
More information is needed, as an eagle is found on all U.S. quarters dated before 1999.
The absence of ridges on some quarters is due to the coin's manufacturing process. Quarters without ridges are known as "smooth edge" quarters and are commonly found in uncirculated coin sets or special collector's editions. These quarters are legal tender and can be used just like regular quarters with ridges.
Any of the "State Quarters" (1999-2008) found in circulation are only face value.
