I don't do a lot of quarters.. but a do have a favorite.. a gift from my then 10yr old son so it would be special even if it was a slug.. My boy has taste
There's something very classic about the Morgan Shield Earring Quarter that I like a lot. (Not mine.) I keep thinking about the Shield Earring Quarter and Dollar when I see the reverse design of the current Shield Cent.
Okay, I'm mopping up the drool here, I love love love quarters, I don't take good pictures, but my favorites are probably my Seated Liberty 1860 S quarter - damaged in a PCGS slab (AG damaged), it's not pretty, and my 1916 SLQ (my pic) that is a FR 02 damaged, ha ha ha, yeah, it's not pretty either. I have a 1929 quarter Full Head MS63 that is really pretty. Here's my most expensive purchase to date - I bought it raw for $500 and I think ICG was a bit cruel on this one....
Current favorite. Thanks @Beardigger. And this is definitely my favorite design on a quarter. I think the eagle in flight is really neato.
