These are very fine pistols -- incredibly well made, accurate and totally reliable, even with JHP's in my experience. However, as the .32s were made in such vast numbers, condition is EVERYTHING to the true Colt collectors. There is a significant monetary difference (maybe 100-300 dollars) between 100% and 98% condition. The Blue Book, etc. are not a real accurate reflection of what these will bring on the current market, and are a bit low for minty guns in my opinion. If you ever plan to fire it, you should be aware of the importance of mint condition and look it over carefully before deciding to shoot or carry it, as you could devalue it severely even with only a little use.
The box,etc. add significantly to its value. If you think you want to carry or shoot a Colt 1903, I'd see how cheap I could get the second one, as it can take all the abuse and let your mint one stay pristine. I'd try for $200-225 or so on the second one. The consecutive serial numbers are an interesting feature of that pair.
For those with a shooting interest in this model, the aftermarket mags for these NEVER EVER work properly in my experience. Correct mags may or may not be "two-tone" depending on when they were made, but will be stamped "Colt .32 Auto" or similar on the baseplate. A few have their baseplates pinned on with two round pins, and most have two very heavy dimples on each side where they were crimped. These make wonderful carry guns, even though they are not tiny, because they are so slim. They are very easy to shoot well, despite the small sights.
About the only part I have seen wear on them is the safety. As they come from the factory, they click on and off like a 1911 safety. As they wear, the click fades and eventually it becomes more of a friction fit. The safety is low profile, however, and if reasonably tight, is very unlikely to work its way off; moreover, the grip safety is another good backup feature on these guns. I've taken my .380 Colt 1908 to an IDPA match for fun and had a blast with it-- didn't do bad at all, either, to the point that after the match people were crowded around asking about it and wanting to know where they could get one!! The .380's are especially sweet but much less numerous, and tend to be priced higher than "user" condition .32's as they are still much in demand as shooters.
