Collectors value Luger pistols most highly when they are as close as possible to the original manufactured state. Very high percentage full original finish coverage with all matching parts in excellent working condition.

It takes time to learn how to judge these things. The more rare and desirable a pistol is, the more likely it is that someone will try and fake it.

Since there were many eras and different countries that used uniquely marked and manufactured Lugers, there are many ways you can focus collecting.

Manufacturing quantities for most unique Luger configurations are known. The combination of rarity, condition and demand determine valuation and also potential for increase in value if the pistol is properly maintained.

Since you're discussing quite valuable pistols, consider getting the appropriate reference books and studying them before buying anything. You'll save money in the end and have some unique skills for the future.

Yes, the collector reference books are expensive, and many are out of print. They are still the best way to approach what you want to do.
