are unmarked bottles worth anything?

[hokeypix]

I picked up a few of those as well. I can post some photos, if anyone thinks it might be worth it....can there be value in them, even if not marked with a company logo? thanks.

Yes. If they are crude and/or have good color. Older the better. Preferably pontiled.

what are the most desirable colors?

Hi Hokeypix! welcome to the forum[] Everyone has a favorite color..some collect in certain colors..a general rule is if it is not common for the bottle it is worth more..some colors that are usually good are, cobalt blue, deep green, amber, or a pale yellow..also shades of purple, caused by the bottle being in the sun..one of my favorites..sounds like you have some cool bottles..hope this helps you...take care!

The value of plain bottles depends a lot on what type they are, most good goldfield's pickles/salard oils are unimbossed but still worth a lot, most plain aerated water bottles (Codd's, Torpedos, huch types etc.) are worth next to nothing even if they are an odd patent/colour, exeption being cobalt blue or previously unheard of patents.
unmarked medicine/chemist bottles are not worth anything nor are most others unless as Oldtimer said they are early and pontiled.
