Personally I get more of a thrill from bags that have the glued-in number than from those that are stamped. I don't know if they are considered by all collectors to be more collectable. (The funny thing is I find them more exciting than the earlier bags that had no number!) No one outside of Coach knows the exact dates they used them. The theory I have is that they may have used the glued-in numbers at the same time they were using stamped numbers. It allowed them to add the number after a bag was completed. It's possible that the stamping equipment was out of order for a period of time and they had a backlog of bags that needed numbers. Or, some workers had access to the machine that stamped the number with the creed and others didn't. I've seen no evidence that it was only used on certain styles. It seems to have only been used during the time that the creed included the copyright symbol. The dates that the copyright symbol was used are also not clear. I have a bag from 1980 that has the glued in serial number and the copyright symbol. However, apparently Coach used the copyright symbol before they had obtained a copyright. To make things even more confusing, there doesn't seem to be any evidence that bags with lower numbers are older than those with higher numbers.Can someone please tell me during what period Coach used the glued-in leather strip for the "Coach bag registration number".
Was it it only used for certain styles or was it used on all bags during that time?
Are bags with this strip considered to be more collectable than those with the stamped serial number?
