Great Britain Stamps: Tangier Overprints 

And he only shows us the parts of his collection he thinks he can fit into a presentaiton. It's a vast collection and so we're really looking forward to seeing more installments of it. As you point out, its rare to see such complete world wide collections.

Hi Phillip! We're glad you enjoyed the presentation. Having all those stamps in mint never hinged condition is impressive! Pricing collections like that is tricky. I know Sam would love to know what they are worth. Fricing collections like that can be tricky. Here are some suggestions for determining real-time value: Using eBay's advanced search options, search for the stamp or collection and click the box to show only sold items (key). This allows you to review recently bought examples for an estimated price. Additionally, consulting catalogs and estimating approximately 30% of the listed value can provide an idea of their worth.

@@iscny Thank you. I imagine there is a premium for the entire sets of these stamps. It took me time to get it done.
