The catalogue value is in the thousands, I haven't actually taken the time to calculate it but you can see by the photos that this collection contains a lot of higher value key date stamps. Its a mix of new and used with most being used, theres a ton more than shown in photos but the photos show a lot of the higher value ones like the complete set of 1908 Quebec Tercentenary stamps ( the 1/2 cent stamp is mint hinged).
