Found a Penny, a Half Dollar, a Key, and a Guitar Pick in the Parking Lot

Today I took the trash out and wandered around the parking lot. I spotted this penny at the end of a parking space then kept moseying around. 

I had found some trash and was going to throw it away when I spotted the guitar pick and key behind the brick dumpster enclosure. When I picked up the pick, I also saw this Kennedy half dollar! Score! That's the first half dollar I've found.

Have you found any money lately? Even pennies are exciting, I think.

UPDATE:  I went to Sprouts and found a penny on the floor as I was walking out of the store. Yay!

Found 4 Pennies at the Post Office

Today I went to the post office to mail a book and on the counter that's along the side to prepare your mail if you didn't do that at home, I found these 4 pennies. 

Then in the parking lot I found a set of keys and this guitar pick. I took the keys inside but kept the guitar pick. What should I do with it?
