Manufactured by Harrington & Richardson very near that patent date.
H&R does not have a patent dating from 1850 - either you have the wrong company or the date was misread??????????????
That patent date appears on the H&R Model 1 revolver, which is a spur trigger single action in either .32 rimfire or .38 rimfire. Value can reach $200 or slightly more in top condition. sales@countrygunsmith.net

Under $100.
Depends on the model and condition. Anywhere from $10- $200. By the way, those are patent dates, not the date made.
Try Cornell Publications. They have a few books on the company
It is, most likely with that barrel rib stamping, a 1st Model 2nd Variation "Auto Ejecting" model - made before 1890 - earliest production of this variation was around 1886-87. In excellent collectible condition, these will bring close to $300 at auction.
