Can you read the back-mark on the US Great Seal button?

Also the rock is beeping with pinpointed. It is light in weight. Could it be. Meteorite.? How can I test it to be sure

I find a lot of responsive rocks, and I have also not figured out why they respond to the MDs. From what I gather, though, meteorites are very dense and heavy for their size, and the responsive rocks I find are all very light. One of these days I'll save one and break it open to see what I find, and I'll post the results.

I believe that most meteorites are high in iron... check to see if it's magnetic.

Love that button and hopefully you can get a date or time period on it soon.

I found a Great Seal button like that, other than the back looks a little different. I'll see if I can find it again, and post a pic. I think it was from around WWI.

The rock i found in the photos is not magnetic.

A lot of things can be non magnetic. Aluminum for example. Actually most meteorites will have some magnetic pull with common household magnets.

I can see the "bur" from "Waterbury" in the back mark I believe. Judging by level of wear I would have to say WW1 or 2. Hard to narrow it down further than that in its condition.

Deb55's US Army "Great Seal" button has a raised border encircling the emblem, so it is post-1910... but it also lacks the "black finish" that was applied to these buttons until 1923, so it was manufactured sometime after 1923.

Its backmark appears to be "Superior Quality" -- which is almost useless for dating a 20th-Century button.

The rock looks like a piece of slag from a smelter and the button appears to be Vietnam Era possibly 1960's to almost present.

Thanks for photos showing your 1923-to-present version of Great Seal button after cleaning. They show it is has gold gilt (goldplated), so it is an Officer's button. The backmark photo shows what I suspected -- it is "Superior [star] Quality [star]" and is written in late-1800s-to-present non-serifed (plain block) lettering, with three circles of dots. That specific version of Superior Quality backmark is from the first half of the 20th-Century. Since then, most backmarks have gotten "plainer," omitting unnecesssary backmark detail-work like the triple circles of dots.
