The model 38 Marlin is a very unique action. It breaks open like a shotgun, and was not made for many years. I see these 38's going in the $150-$250 range, unless they are in excellent condition. The serial number is the best way to determine a firearms age. The serial number for your gun should be located on the side of the tang, observable when the stock is removed. The patent dates also indicate that this should be your serial number placement. Your gun will probably also be lacking the Marlin "Bulls eye" found in the later production 38's. As far as I can tell there more than 24000 Model 38's were manufactured from 1921 through 1930 and your 38 probably is among the first 11000 (the serial number will tell). An "A" prefix serial number is the subsequent series. The "A" prefix guns carry additional patent dates, external serial numbers and the "Bull's Eye". I do not know guns but here is what I see on my Marlin 38. External serial No. 10680 stamped just ahead of the trigger guard (without "A" prefix). Patent dates as in the above answers with additional dates through June 6, 1922. Bird's eye present on stock.
I have one and it's a 22 caliber.
In order to determine the exact value of a Marlin model 1892 22 caliber octagon barrel lever action firearm, a couple factors would need to be taken into consideration. Most importantly, the condition of the firearm.
I believe I have a Marlin No.18 pump action octagon barrel single shot rifle. Would upload photo but cannot locate this option.
Depending on condition, a Marlin 1895 lever action in 45-70 sells for $400-$500.

Roughly 1900. Since Marlin mixed serial numbers between models on the early levers it can be hard to pin down exactly. As to caliber, look on the top flat of the barrel. sales@countrygunsmith.net
The Sears Model 42DL .22 caliber rifle was manufactured by Marlin Firearms, their Model 80. Check with Marlin for parts availability.
