✅ SOLVED Two tiny pins

[Crispin]

Non magnetic, they don't dissolve in water. Not silver. Not lead, doesn't melt. Found them on same beach not near each other. They seem kinda odd. Anybody know what they could be from?





Bonus ID: very light, seems to be Aluminum alloy, was coated with something that flaked off. I'm thinking burning from a ship stove...

Someone has been real busy cleaning up trash and goodies from the beach. Now that those are out of the way, hopefully the really good signals will start to ping your' metal detector!

They appear to be rivet pins.
Should be malleable metal.
An attempt of an example of where you may see them not peened on small end as normal rivets use sees, would be in a name plate attached to an electric motor base.
Or an iron base for something where a pilot hole suffices where backside of rivet is not accessible.
The rule of dissimilar metals corrode would apply to their use ,like aluminum rivets on an aluminum pot being compatible. Exceptions occur, maybe from availability of choices.
Securing a plate to wood or cast iron not as critical.
Here's some ship equipment /machinery nameplates.
