You might find someone who attaches extra value just because it was the first but condition will be much more important than the fact it was first. If it was pristine condition and you could add in the fact it was the very first of its kind you might slightly increase its value. But as a well worn example that fact alone will not make it top dollar.
People collect all kinds of "extra value" items. Some like consecutive serial numbers. Others like guns with serial numbers which end with 000. Or you can collect the same serial numbers in different guns. For the dyslexic you can collect guns with palindrome numbers, serial numbers which are the same frontwards or backwards. With such small markets demand may be slight to all the rest of us. A guns value is what you can get for it and it takes only one buyer to make the seller happy.
