2 1968 Quarters One Mint Mark, The Other Not

Not sure of what your question is, the one without a mm
was struck at the Philadelphia mint if that is what you are asking.

Also, the mark is a D

@van, first welcome to CCF. Second, yes these are typical, well-circulated quarters and only worth face value.

From looking at your posts it seems that you are just pulling coins out of a change jar and asking if thy have value. are you doing any research on your own before posting and asking others to to research for you?

The Washington quarter was first issued in 1932 to honor the 200th anniversary of George Washington's birth. The original Washington quarters were struck at the Philadelphia, Denver, and San Francisco Mints and featured the respective Mint Marks of each Mint until 1964. In 1965, the U.S. Mint made dramatic changes. First, the composition of the Washington quarter changed from .900 silver to copper-nickel due to the rising price of silver bullion. And second, even though the coins were still made at all three Mints, no coins were made with Mint Marks in 1965, 1966, and 1967 so no mint marks on these years is normal. Previously, only those coins from the Philadelphia Mint were struck with no mint Marks but it is impossible to tell which 1965, 1966, and 1967 Washington quarters were made at the Philadelphia, Denver, and San Francisco Mints because none has a Mint Mark and they all look alike.

Mint Marks returned to Washington quarters in 1968 so you will find D for Denver, no mint mark for Philadelphia, and S for San Francisco for that year. Values depend many times on factors such as condition, where low grade circulated coins are worth only 25 cents, while extremely high quality examples which normally arent found in pocket change and then are sent to be graded at a cost may potentially be worth more.

From PCGS: The 1968 Washington quarter has a very large mintage making it easily obtainable from circulation in circulated grades. In uncirculated grades it is also easily obtainable in MS60 to about MS65 condition. Examples in MS66 are scarcer but can be purchased at a small premium. In MS67 condition it is really tough to find with many examples being graded and sold at a significant premium but probably still hundreds of examples are out there. In MS68 condition it is truly scarce with less than handful of examples known and none being known in finer condition.

Thanks Nick10, dont want to add too much info for new collectors in each post. The 1968-D Washington quarter has the lowest mintage for any circulation strike Quarter struck from 1965 to Date. Although it has the lowest mintage it is still fairly common and examples can still be found in circulation. Uncirculated examples can also be purchased inexpensively up to MS65 grades. In MS66 grades examples are usually pulled from rolls or sold as singles. in MS67 condition they are scarce with about 200 to 300 examples known. In MS68 condition they are almost unheard of with less than a dozen examples available and none being graded finer. Values do not jump until MS67+ (52 in MS67 to 375 in MS67+) or MS68 (3,400). A bit lower we have 14 in MS 66, 28 in MS66+ and 8 in MS65. A MS63 is only $1 and thats graded which costs fees to grade so thats why most dont get excited about circulated and low mint state examples...

Thank you!
