Single Action Army or New Service?
price is based on model, condition and date of mfg. if your colt is an early single action revolver then it would have been made about 1880. good single actions command a high price. but you will not command a high price without full details as to markings and overall condition as well as pictures.................if it is a modern colt revolver then the high price will not be there.................
100-1000 usd
around $150 and up, depending on condition,markings,and history.
depending on condition....$2,000 = $3,500
You will have to define "good". Cowboy Action loads are low pressure lead bullet loads.
Made in 1876. Your description is lacking in details to say the least. Caliber? Barrel length? Finish? Overall condition? Any history on it? Does it have a letter from Colt. Broad range 800-8000
0-150 USD or so
Without the serial number and a very good description to include caliber, bbl length, all markings, accessories, box, papers, any engraving, condition, there is no way to even hazard a good guess.
100-400 USD
