I recently got a Desert Eagle .357 in a trade. This model is a very early one. Probably the first one to two years that they were made. The serial number is a low 12XXX. It is all blued with a little wear. I know that these guns were started with the serial number 3001 from the little research i have done. My question is, is my gun worth any more because of its low serial number? If not, what is a fair cash price i could ask? Thanks in advance for the feedback.
