Bottle Show Finds

I went to a bottle show in Tallahassee, Fla. last Saturday with a good friend. I didn't buy any bottle but did pick up some odd little pieces. One vendor had some coins and buttons that I looked through. I picked out some buttons, a large cent and a odd looking coin. He gave me a very fair price but I had to go for more so I asked if he would throw in one of the three seated dimes he had. He looked through them and laid one on the counter and said I could have it. It was the most worn one of the three.
So, after getting home I was looking at the coins and found that the large cent was two of them glued or soldered together so "heads" showed on both sides. Then I checked out the unknown coin and, with the help of my knowledgeable friends, determined it was a counterfeit $5.00 gold piece. Finally I looked at the dime . The reverse was worn but still legible. But, it looked like a pin type attachment had been added.
