My son found this unknown metal object buried in our back yard. I did the search on the "cerro matrix". Which is a combination of metals of fusible alloy for repairs. BUT, when I did the search on "C DE P" that is located above the "cerro matrix". It's something to do with an old rail system. On an old "Brakeman" badge hat like this pictured:

The object:
weighs at least 5 lbs
magnet does not stick to it
And no other markings that I can see
Thanks
