Well I would call 1860 a guess, patent dates don't count....
It depends greatly on Type, Model, Variation, and very importantly condition of which we have none ;) There's 3 types, 4 models, and a good 15 variations so it's nearly impossible to describe them all. If you click the service desk or send mail to Remington@remingtonsociety.com I can help you identify what you have.
No way to answer without a serial number and complete description
it depends on the year of the Remington 1100
What year was the Butler derringer made. Serial 22500
100 USD or so
Need a DETAILED description of ALL markings and condition.
Saw one for $200 earlier this year
Please look at the date again, no U.S. half-cents are dated 1860. 1857 was the last year of issue.
Value could range from 100-1000 USD dependingon EXACTLY what it is.
What kind of Remington 22? Also please check my bio page about describing your firearm to get the best estimate on value.
Go to remington.com.
Remington didn't make a 44 pump and I suspect the year is actually a patent date your reading on the barrel which is not the manufactured date. If it's a 22lr with no markings it's probably a model 12. Value is GREATLY determined by condition for which none is supplied.
Depending on condition, value may be $300-450. Age can be determined from a 2 or 3 LETTER code on the barrel- left side, just in front of the reciever. The Remington Collector's website has a chart showing month/year using the letter codes. Google search Remington BLACKPOWDERX for the chart.
