✅ SOLVED Lead 2 piece buttons or just impacted projectiles?

[muerte33]

Could these be old lead buttons, or just impacted projectiles?

The weight on these are from left to right:

1.6 grams
1.5 grams
1.4 grams

They were all found within about 50 square yards of each other in sandy soil.
I tumbled them too with some coins, so any patina would be gone.
Thanks!

Here is the other side:

Maybe nail caps?

Maybe nail caps?

That's what they are. I've found a lot of them around old buildings with sheet metal roofs. Here's an example.

TomPA and relic nut are exactly right.

Thanks fellows for the ID, I think that "nailed" it.
