These old GN quarters are scarce in AU or above and I believe are worth more than $100 in high grade. There are also color variations (that may or may not be as-made) and variations in the hotstamp. I still need the one with small 25.

Here is a scan of two in better condition and with slight color variations. The depth of the hot-stamp is also different, but doesn't create a variety IMO. Lots of these are worn almost smooth.
