Depends if you found it in the ground or at a local fleemarket. As the bullet seems to have hit in the same place on all of them you would assume its fake but from what happened in the Civil War there's got to have been hundreds of bullets that hit and stuck in equipment. Lots of British families have the Bible or tobacco tin that stopped a bullet from finishing off Great Grandad in the First War.
When I was driving from San Francisco to Vegas we stopped for a drink at a small town general store/fruit and veg place. No one around so I walked to the back where there was a bit of noise and there was a guy chipping out "genuine" indian arrow heads. They fake anything where there's a buck to be made.
minie ball tip would be flattened more
they turn $150 relic into $500+
by doing that - if someone does not know better
I saw one on Amer.Pickrs - that one looked really fake
That particular style of buckle was not used during the civil war. The arrow style hooks are a dead giveaway. What you have is a cheap reproduction that is somewhat popular with civil war reenactors. It feels heavy because it is most likely filled with lead. Which is common for these fake buckles.
the brass buckle appears to have been artificially aged, by way of burying it in a bucket of sand and pissing in it for a week to cause the darkening & aging effects
I agree the tip of the bullet looks like it is still round and should be deformed from impact since it's made of soft lead
