I bought this in a gun shop in Atlanta that sells old firearms and the guy said it’s from the civil war from Atlanta history center I wonder if it’s real original period from the civil war if so is it a sharps or a spencer? Lmk

Many probably know more than me but from what i understand the large caliber rim fires were more or less obsolete by around 1900… I’d say it safe to assume it’s from the last half of the 1800’s

The Sharps carbines of the Civil War period used linen cartridges, not metallic. Spencer cartridges were copper-cased rimfires but the proportions look wrong; the case looks too long in comparison to the bullet to be a Spencer cartridge, though it is hard to say for sure from a photograph. The quarter for scale does not help much. Measurements of the case length and diameter are necessary for an identification.
Does the case have two tiny and hard-to-see dents opposite each other just above the rim? If so this would identify it as a post-Civil War inside-primed cartridge. It could also be a rimfire, though the rim looks a little thin to hold much of a charge of fulminate. Without any measurements my best guess, just going by the length-to-diameter ratio, would be that it is a revolver cartridge.

It is a 56-50 Spencer carbine round (Rimfire) used in the war between the sates. Seems to be of the CW time period, because there is no headstamp. however they were still being made up into the 1920's

I believe this maybe a match for your cartridge but only precise measurements will confirm that.

Description: Decent cartridge known as the .50-45 Cadet cartridge. These were manufactured at the Frankford Arsenal and have a .50 bullet with .45 grains of powder.

The dents I asked about establish that your cartridge is a post-Civil War inside-primed center fire. They are there to hold the primer in place inside the case, instead of the primer being pushed into the back of the case from the outside as is done with later style brass cases. If measurements confirm that it is indeed a .50-45 case, it is of the type used in the Sharps carbines converted to .50 centerfire in 1867.
