Value of block of 4 stamps?
I am almost new to stamp collection and I have got a few "block of 4 stamps". Somebody told me that "block of 4 stamps" are worth more than they would have been, had they been separated individually.
Fair enough...However, the "block of 4 stamps" which I have has torn perforations. Please have a look below:
Could somebody please tell me how much is this stamp block with torn perforations compared to the same stamp block without torn perforations?
