Flat button ID

[Scrappy]

On the off chance this button design is of importance, I'm hoping to see if anyone can get an ID. Thanks

The button folks ID many flat buttons as being flat tombac button. I seem to make out antlers, maybe:

It's a copper button

Looks like it.
Tombac is an alloy formed from a mix of copper (84 - 90%) and zinc (10 - 16%) and sometimes the addition of arsenic which produces a White Tombac. The zinc content is what makes the button surface stay shiny emulating polished silver. Early Tombac buttons date from the 17th century (Pimple Types) but most were mass produced in the Late 18th century most were engine turned on a lathe, others were hand engraved with different themes like hunting scenes & Floral designs probably sold as gift sets, these are allot rarer than the more common machine turned types. On the reverse most have a raised cone shaped base for the soldered copper wire shank the smaller types also shown below tend to have iron shanks ..Generally made for civilian use but also made for the Military of the period. Here is a general selection of what can be found on sites across Britain.

By that line there, it looks like a sportmans button.

It's not a tombac. It is likely made between 1820 to 1840s. I think it is plain with just some crude built up on it. Fairly common for that era.
