How much is a 1776 to 1976 quarter worth?

I'm curious to know, what is the estimated value of a quarter coin that spans from 1776 to 1976? Is it a rare find or does it hold a special significance in the world of numismatics? Could you elaborate on the factors that might contribute to its worth, such as its condition, mintage, and historical significance? Additionally, are there any specific markets or collectors who might be particularly interested in acquiring such a coin?
