Definitely worth it, after the initial cost it becomes a free hobby. Your finds look relatively old I’m not an expert but if I had to guess I’d say late 1800’s ish… minus that eagle I think that’s just a common beer bottle
PotteryShardsss, welcome to TreaureNet's "What Is It?" forum -- the best place on the internet to get unknown objects CORRECTLY identified. (Never trust what Ebay sellers say in the ID of what they are selling.)
I have to also mention, Worthpoint is "imperfectly reliable.")
Just in case you don't already know:
The shard at upper left in your 2nd photo-post, which has dark brown glaze and coarse (large-gauge) "threading" on an internal tunnel's wall is most probably a piece of a broken ceramic telegraph-line insulator. The type you found is from the late-1800s through the first half of the 20th Century, and statistically most likely from the middle of that time-range. The insulator was screwed onto a threaded short wooden rod on the telegraph pole's cross-arm.
