Are we sure those are pinfires?
It's hard to tell, but they look almost like Adams-type lipfire cartridges.
They also look as if they have jacketed bullets, which would be HIGHLY unusual.
If they are lipfires, they might be more valuable than the handgun.
Can we get some good, clear photos of the cartridges, both a side profile and a look at where the hammer would strike?
