A Eureka Moment!

I was sorting through my collection the other day, when I came upon a copper coin that was barely recognizable. Since my coin club meets next month,and I have plenty of vacation time on my hands, I decided to try to ID this coin myself. Where did I acquire it?(in a batch of old foreign coins I picked up at an antique shop!--I almost threw this one away thinking it was worthless).At first I thought it must be a non US coin(a world coin) since it was thrown in with a mix of foreign coins. After looking at some world coin inventory and not recognizing anything close to mine, I gave up looking for a while. I was organizing parts of my collection and came across some old RED BOOKS...Looking through the pages I spotted the section on colonial issues. Sure enough there were coins that looked like my worn copper. After several hours of reading and web surfing, I narrowed it down to 1788 Connecticut copper, a left facing bust (Miller #15.1-L.1)Rarity 5 AG condition, value about $50? . The real value lies is in the discovery!
It was a real rush to discover this on my own and to realize that my oldest US coin is now about 220 years old(around the time of Ben Franklin, George Washington and Thomas Jefferson!)This was one of the greatest moments in my lifelong coin collecting hobby! I will try to post a picture...it's very worn (Auctori Connec show with a very worn bust on one side while the only thing showing on the other side is INDE ET). Anybody else have a challenging story of discovery?
