A general question if you please. Last night as I was soaking more
stamps I ran across a number of plate blocks of older stamps. I
understand that MNH PBs are collectable by some folks and was curious if
the same holds true for used?

What got me wondering was as I picked up a set with tongs, the PB
portion decided to seperate from the block of 4 stamps. I guess it had
been folded numerous times along the perfs as just the weight of picking
it up by the PB was enough. That made me wonder if I'd mesed up
something I shouldn't have - not for monetary value but from a hobby
collectability standpoint in general.
