Really nice find! Congrats! Beware on that patina! I recently found a CT copper and I noticed a small spec of corrosion and I tried to chip it off and it was like unraveling a sweater. I decided to scrape the rest of it off because it just made it look like a mess. It ended up still looking great under the patina... but it would have looked better if it retained it. I like to think it was out of my control.
