So as I am organizing my collection I am coming across many doubles and in almost all the doubles one issue has a bar code while the othe has an image of Spiderman or some other image. The price is the same but I noticed one will have the UK prce as well as the USA and Cdn. Why is this and whats the diffence?

I'm about to start cataloging a lifetime of comic book hoarding with some rediscover. I'm 53 years old and have been hoarding comics starting when my father was bring them home before I was born. Most of my obsession or my money investment took place in the 80's and early 90's. I haven't a solid count on the numbers but I guess there is about 4000 to 6000 comics. I'm going to start cataloging using comicbase of course and would love any tips and where to start.
