I am almost new to stamp collection (relatively speaking) and I have got a few blocks of 4 stamps. Somebody told me that block of 4 stamps are worth more than they would have been, had they been seperated individually.
Fair enough...However, the block of 4 which I have has torn perforations. Please have a look below:
Could somebody please tell me how much it this stamp block with torn perforations compared to one stamp block without torn perforations.
