help with some buttons please

[BIGHEAD]

Hey guys I found some cool buttons that I can't ID if you could help it would be great!! the first button has a crown and a coat of arms on it. I found it near a musket ball but it has no back so I can't tell if its old or modern. The naval button comes from a 20"s To 50's dump site but looks to be made of plastic? It has no markings so I can't tell. the last button has an indian head on it. I did a check on the net and found all kinds of indian head buttons but none that look like this!! If you could give me a date it would be great. Thanks for the help!! Bighead

First button is a modern blazer button.

Second a US Navy button, date?

Third, I'm unsure of..... Looks civilian 1920s

The navy was using hard black rubber buttons in the 1850s (ish) but I've not seen one in that style or seen one without a back mark. Interesting piece, it deserves a closer look. 


I agree with Crusader on the other IDs.
