There were eagles on the back of all U.S. quarters dated 1998 and earlier.
If by "type" you mean design or metal content, all U.S. quarters dated 1964 are made of 90% silver / 10% copper and have the same design. The only difference is whether there's a mint mark under the bow of the wreath on the back side.
All Washington quarters dated 1932 to 1964 had the mint mark on the back under the bow of the wreath. No mint mark = Philadelphia D = Denver S = San Francisco (up to 1954)
Many U.S. coins have a mint mark to show where it was minted. On modern quarters, the mark is just to the right of Washington's hair ribbon. P stands for Philadelphia, D is Denver, S is San Francisco, and on older quarters there is O for New Orleans. On quarters minted before 1980, there was no mint mark for Philadelphia. For silver Washington quarters dated 1964 and earlier, Barber quarters, and Seated Liberty quarters, the mark is on the back just below the eagle. Then with Standing Liberty quarters, the mark is on the front, just above and to the left of the date.
Check that coin again, because NO U.S. quarters are dated 1975.
Washington quarters had their mint marks on the back until 1964. Look under the bow of the wreath, above the R in the word QUARTER. If there is no letter, the coin was made in Philadelphia. A D means Denver. (Quarters before 1955 were also made in San Francisco, "S"). 1964 quarters were made by the billions, so they are only worth what a metal dealer will pay for their silver content.
There is no coin called a QUATER. The name is QUARTER, just like it's spelled on the back. The only dual-dated quarters were issued during the Bicentennial celebrations in 1975 and 1976. All were dated 1776-1976, even the ones minted in 1975.
1964 quarters are worth about $3 each for their silver content. 1965 and later quarters are made of cupronickel and have no extra metal value. There are a few errors among the state quarters but everything else is worth 25¢. Major s/q errors are: > Delaware quarters where the horse and rider on the back (Caesar Rodney, if you care) are oriented the same direction as Washington's head on the front. > Iowa quarters where the corn stalk has one or more extra leaves.
Despite being over 50 years old, it's still worth five cents. There were over two billion nickels dated 1964.
It depends on the quarter. From 1932-1964 silver quarters had the familiar Washington eagle design on the back, just like clad quarters up until the state quarter series. The Standing Liberty quarters depict an Eagle in flight, the barber quarter has a heraldic eagle on the reverse and earlier coins usually have something stating that it is a quarter of a dollar.
The only 1965-dated U.S. coins that contain silver are half dollars. They're only 40% silver, as opposed to 90% for dimes, quarters, and halves dated 1964 and earlier. Nickels are made of copper and nickel, not silver. The only nickels that contain any silver at all are the famous "war nickels" from 1942-45. They can be identified by a large mint mark on the back. They contain about 35% silver.
The mint mark on all Washington quarters dated from 1932 to 1964 is on the back side above the "R" in the word Quarter. No mint mark = Philadelphia S = San Francisco D = DenverOther datesQuarters dated 1965-67 don't have mint marks. Starting in 1968 the mint mark was moved to the right of the tail of Washington's wig, and in 1980 Philadelphia coins started using a P mint mark.
