Welcome to Tnet, Nice to see your finds. The more you swing the coil, the more treasure you will find. "So much Tara Firma, so litttle time." It took me 4 months (150-200) hours to find my first silver coin. Good Luck and again welcome to the forum.
Cool finds, I used to live in Bradenton, are you allowed to detect on...grrr. can't think of that island out there. The one with the guns...lol, just thought about the turtles, so no, I think if the warden out there saw anyone digging, it'd be jail time. I kinda wish I was down there though because am new to detecting and know some cool places that I'd like to check out...
I remember, Egmont key, that would be an awesome place to search!
