Help with 1 piece Eagle button (solved! Eagle A, 1821-1840)

The US made a concave one piece eagle button starting around 1824 and continued until about 1854. I couldn't make out the eagle much so I don't think I can tie it down much better than above. Regards.

By the number of bands on the back and the stars in the third from the outermost band, it looks like a pre-1830s to late 1840s Robinson, Jones & Co. If you can make out any letters that would make up the words 'Extra' and 'Rich' with a '.*.*.*.' in the same row and between the two words on both sides, that may be it. It won't be the same as the pic below as I see no words in the second from the outermost band but it could be a variation as RJC is the only button maker I can think of that used that number of bands on the back. That's all I can gleam from the pics.

Thanks! From my own research and this and several other forums, I believe it to be Tice AY199D19 (Albert's AY62, not sure which subtype). It would be an early artillery button with the A worn off. I looked for similar backmarks among the GS and I buttons in Tice and didn't find any, but I did find AY199D19 with the backmark " *.*.*.*.*.*.*.*. ". Another forum also showed me this example of AY199Ds4, which shows the same device and backmark but in cuff size. I found a dug example of the coat size on another forum with the same backmark in a series of concentric rings which appear to match my button as well as a matching device, misidentified as AY199Ds4 (likely by using relicman's site and failing to take into account the size difference).

So I do believe that's it, 1821-1840 US artillery button Tice AY199D19.

Thanks for the help!!

I think you're right. Tice IDs it as being produced from 1821-Early 1830's. Well done.
