Should I Be Pulling '65-'69 Coins?

1965-69 halves are worth keeping as those are 40% silver. 65-69 clad dimes and quarters are common and not worth keeping unless you have BU pieces

There are silver nickels,but they are dated 1942P through 1945S,commonly refered to as War Nickels.They have a 35% silver content,and can be told from non silver issue by the location of the mintmark on the reverse above the dome.
After the War they go back to original composition,and the mintmark was moved back to the lower right corner of monument.

Pre-1958 nickels seem to carry a premium in roll quantities. All pre-1982 cents also carry a premium now.

Its the last year of copper pennies. sometime in 1982 the went to the copper plated zinc pennies, eveyone calls them zincolns now. Thats why there are like 7 verities of 1982.

Agent Mulder, there are some VERY VERY RARE (please imagine that underlined and bolded) silver 1965 quarters--they're errors, however, and you shouldn't expect to ever find one in your drawer. If you do, you can tell them from clad the same way you would tell a 1960 from clad if you didn't know it was silver: the sound, the solid-silver edge, and the weight (clad quarters are lighter).

However, again, the caveat here is: run a register every day for 50 years in the middle of New York City, and you'll still probably never see one. All odds against.

i think I actually have a 1965 silver quarter, I either let my aunt keep it or I took it, I let my aunt keep that one, but I know for a fact 100% that she has a 1965 silver quarter, how much are they worth?

The easiest way to determine whether a quarter is silver or not is to weigh it. Quarters were never silver clad, they were 90% silver alloy through 1964. The only way a quarter could be silver clad is if quarter blanks were punched from the 40% silver clad metal stock intended for 1965-1970 half dollars. Since half dollar metal stock is thicker than quarter metal stock, the coin would be thicker and heavier than normal.

The outer layers of CuNi clad coinage can sometimes obscure the copper core on the edge, that is the most likely explanation for your 1965 coin absent a weight.
