a date
All US Quarters made in 1975 & 1976 have the dual date 1776-1976 so if the coin has a date of 1975 it's not a US coin.
US one dollar gold coins were last made 1889. Make sure you used the correct date. If your coin has a different date ask another question like the one above but substitute the date with the date on your coin.
On the "heads" side of US coinage there is a date, that tells you when the coin was made.
No US quarters were struck in 1816.If your coin has a race car on it - something that didn't exist in 1816! - look at the date near the bottom rim; it'll be 2002 because the coin is a State Quarter honoring Indian, which joined the Union in 1816.

Presumably by "old buck" you mean an old $1 coin. However saying a coin is "old" isn't enough to have any idea of its value. The date, possible mint mark, design, and condition are all very important. Please either: - check your coin again and post a new, separate question with that information - look for existing questions with the wording "What is the value of a <date> US silver dollar, where <date> is the date on your coin.
