They are impractical and we have a much better system now. Also Roman numbers are not infinite.
On converting between Arabic and Roman Numbers: M IN ROMAN NUMERALS is written as 1000.
A U.S. revolver from the civil war can go for as much as $2000
Not much.
The Romans established a navy with the new tactics of boarding rather than ramming, and so captured Phoenician ships in battle. The corvus (raven beak) boarding plank had a spike which both locked the ships together and allowed the Roman infantry to board and capture. This was adopted because the Romans, who did not have a navy to speak of at the beginning of the First Punic War, built a fleet from scratch. The Roman sailors did not have enough experience to perform the complicated manoeuvre required to ram the enemy ships. The corvus made up for this and brought success in battle. However, it had the drawback of making the ships top heavy. Many ships sank in storms and the Romans lost thousands of lives. The corvus was dropped in the last battle of the war and the Roman fleet won. The Roman navy had come of age. The corvus was never used again. The Roman navy improved so much that in the Second Punic War, the Roman navy was superior to the Carthaginian one even without the corvus.

nothing really not much navy at all
Converted to Arabic notation (which pretty much everyone uses nowadays), it's 1009.
The Navy revolver was not .44 caliber (it was.36 caliber), and was not made in 1843. Without seeing the gun, will tell you it is likely you have a reproduction of the Colt revolver made in Italy by Pietta. You will need a hands on appraisal by an experienced dealer or collector. Modern day reproductions are in the $200 range, depending on condition. PS- Ormsby invented the machine that performed roll engraving. While he was an engraver, his actual engraving was for printing plates for bank notes. Not guns. We have been asked about a revolver with THAT serial number at least 5 times, reinforcing the belief that it is a reproduction.
