Hello everyone, I've had these coins for awhile now and am just absolutely stuck. I like to try to ID coins on my own, because I always learn something that way, but I've gotten to the point of needing some help on these three. The first two I'm sure an expert will be able to ID fairly quickly but the third coin is probably a lost cause, you'll understand when you see it. Any and all help/info will be welcomed and appreciated. Thanks in advance for your expertise!
Coin1


Coin 2


Coin 3 (The lost cause)


Thanks again for the help!
