How much can I get for it today
A patent number will not identify the gun but only some feature that was unique enough for a company to get exclusive rights to use it. It may have been used on several models by that company and they could have sold the right to use this feature to other companies, so it could be on hundreds of thousands of guns manufactured over a century or more. Winchester is still using patents issued in the 1890's on guns made today. Of all the things marked on your gun, the patent number is probably the least useful to identify the gun. Now, if that is a SERIAL number and you can tell us what manufacturer's name and model number are on the gun, we may be able to give you a year of manufacture.
If that is a US Patent, you can look it up on Google, and tell when the patent was issued, but it cannot date the gun- other than we know it would have been made AFTER the patent was issued.

Patent LeatherYes, Patent leather is made from real leather, with a finish originally made from various oils (whale oil, linseed oil etc), and lacquers such as shellac, and a colour, most commonly red or black.Modern patent leather is finished with a mixture of acrylic and polyurethane which gives a longer lasting more scuff proof/crack proof finish.It is however common to come across fake patent leather which is some man made fabric with a similar 'plastic' finish to it.
The last patent date will tell you that it was made that date or later.
