Earlier this year, I sold a non-consecutive pair of each, the numbers were less than 50 numbers apart. All four were unfired but had no boxes or paperwork. I sold the 1851's for $1,250.00 shipped and $1,100.00 shipped for the 1860's. There have been several of each on gunbroker in recent months. Colt also sold the 1861 in stainless but there were less than 25 produced.
