I assume your single action is pre-war ? If so, then made about 1907. As to the caliber, check markings on barrel. that should give the caliber.......

$150-$200
what can you tell me about a colt single action 45 caliber with a 7-1/2 in. barrel serial number 52154
1958
Many .22 caliber rifles made before 1968 did not have serial numbers. This would include your Marlin 100.
if a single action made about 1877 is the question make a 'number' ?????
50-300 usd
Pretty much impossible to value with just the sn and caliber. 10-1000 USD range
Your Model 1885 Single Shot Rifle (high-wall) was manufactured circa May 1891.
