I just received a pane of the "Post Office Murals" stamps. It comes in a pane of 10, but there are five designs, meaning each design has a duplicate. My plan is to use one of each design and collect the duplicates. However, because these are self-adhesive stamps, I need to leave them on the backing paper, which means I need to cut that paper to separate them without damaging the stamps (unless I store the whole pane with half of the stamps missing). How can I best go about this? Are there particular tools that collectors use for this job? Is there a particular arrangement I should use them in to minimize the possibility of damage? (For example, I assume it would be easier to cut out stamps that are on a diagonal to each other versus being next to each other, as they share less real-estate. However, I cannot entirely rely on this because of the way they've been arranged on the pane.)
I'd appreciate advice about what people do in this situation. With a single design it's easy; I'm just making sure to use all but one that's somewhat centrally located, but this is more of a challenge.
If you want to collect a group intact from a sheet, I fold the sheet between what you want to keep and not keep and then use a sharp knife to cut between the stamps while it is folder. Or, you can also just use the stamps around the block and then save what is left.
