Did I Do This Right ?

Block of 10 for 700?

MNH part of the sheet of 50

Area all the stamps MNH?

Yes they are part of a complete sheet MNH

The plate block was broken up by perfs and the recommendation here was to break the sheet up

But why make a new thread instead of continuing the previous one?

I did see the previous post with the whole sheet, and it was coming apart as I recall. Maybe this one can be moved there?

I am trying to get as much as I can for an friend, someone here said this may be worth 700 sorry

Realistically, the catalog value might be ~$700 if condition/grade were better, but it looks like folding has occurred, I can't see the back, and centering is so/so. Based on others I see for sale (no plate blocks, and all blocks of 4), my guess would be you could sell it quickly for $150-$200. Maybe more (+/-$300) if you can wait forever. People are asking between $70 and $250 for a block of 4 with various gum/hinge conditions on ebay and hip.

Looks to me like it has been folded between rows 1 and 2. Also may be some perf separation at far right by the imprint.
