I would say you are doing fine for being new to the hobby! I like the broken seated half dollar, very cool. The steamship badge could have been on luggage,the last piece almost looks like a strap buckle or something. Nice work!
Hi Welcome to Tnet. The first and fourth pic's (front and back i assume?) May have been part of a mold.
Too bad that 1/2 dollar is wrecked, but cool find anyway.
What ever you're doing looks like you're doing it right! If the coin is "as dug" You've accomplished something a lot of us haven't! Found both halves! Good job.
