Value Of Block Of 4 Stamps?

Hello,

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?

Regards

There is probably no difference here. It is not scarce in multiples.

Premiums for blocks of 4 are for certain positions (like a plate number block for this stamp), blocks containing one or more stamps with an error or major variety, or for expensive and/or classic stamps that are very scarce in multiples. Perforation separations like on your block do reduce the value slightly in those examples.

just one perf wouldn't reduce price much compared to a similar block without a seperated perforation.
