Breaking Up A Block Of Stamps

Should you ever break up a block of stamps?
Should you ever break a pair?
Are they more collectable? Thanks for your time....chery

Personal Opinion
1 Does the block have marginal markings?
2, Does it have a Postmark?
3. Modern or block, or classic?

Definitely not.

It remains a personal decision.
I have separated blocks where I have numerous similar (Romania)
but generally speaking, I think best practice is to leave well enough alone.

Greed and personal elitism generally defeats the above.

Blocks Example,
Block of early Australian Stamps George V or Kangaroo

Depending on the watermark, a block can identify its location on the printing plate, identifying valuable errors or variety stamps.

If the block or pair are of different designs, no. If the block or pair shows something only a block or pair can demonstrate (1934 Farley Sheets verses the regularly issues) no.

Earlier stamps have a time a listed premium for a block of four of the same design which is more than the 4 times the single price.

Why are blocks broken up? The album has space for singles, not multiples (sometimes multiples too). Wear and tear of the perforations due to handling--did not start as an intended break-up. The singles sell for $800.00 and the block sells for $4000.00 but there is a buyer every week for a single but only once per year for the block. And lastly, the good old standby, "I did not know any better then."

Edit: Another reason I break up blocks is that for a block of 20 cent stamps, I only need three of four to mail my bill.

Another reason to break up a block is if one of the stamps is a "GEM", and the individual stamp is more desirable to sell vs. the block. Some folks get graded stamp certificates which identify the better centering for which there is greater demand. Nonetheless, it may be better to keep as a block, especially if the number of multiples or size of muliple is scarce for that issue.

To properly answer the question one needs to know what blocks are being spoken of. I break blocks all of the time so that I can place singles on my outgoing mail. Mostly stamps from the 1940's onward that are "face" in nature. There were hundreds of millions of each printed. The block will not be missed. Humans will not even likely remember what a stamp was in one or two hundred years if the planet Earth is still around. Stamps may at least be a quaint historical footnote with a USPS EV truck in some virtual museum.

I appreciate you all for your help. I feel like I have a better understanding..... and what I'm taking away from this is it's best just to leave them as whole as possible. It sure can't hurt.
rogdcam, I believe we probably wont be using stamps in 200 years, but they are way too cool and interesting to be forgotten. Just think of the value of your collection in 200 years...I think my collection may even be worth something by then.... thanks for your time and experience...chery
