That's an awesome assortment of finds - Barbers, Mercs, wheats and tokens - nice hunting!
The California key tag was really cool, but good on you for giving it to the property owners - it sounds like they appreciated it. It's a reasonable price to pay for a good permission, and you still have the photos and bragging rights.
That Pontiac token is super-cool. Congrats on finding that bucket lister. What's #1 on your list?
