What an XF\AU Type 1 SLQ looks like after 50 years as a pocket piece... Why? Because this is the coin that got me hooked on the hobby when I found it in a park back in 1963.
I will bring an Ike dollar, Two Dollar bill, or Kennedy Half Dollar with me sometimes. Whenever I take change out of my pocket I will also grab those, I usually get people pretty interested when they see those "rare" coins and bills. I will also bring a nice coins to the banks to show the tellers whenever I'm getting/turning coins that I search coin roll hunting, the tellers are usually pretty interested in them. Also, I think the coolest thing you were carrying was the 3 cent piece, most people have never even heard of one or knew it existed so that is pretty neat. Funny enough, I love the look of very worn silver Washington quarters, they look pretty nice, nicer than the uncirculated coins IMO.
I agree that the nickel 3 cent is a cool one to carry around. I bought it cheap due to the holes, but I liked that it was still VF-XF details, so a fun one to have around and show off.
