For what it's worth, it's also the lowest serial number I've seen for a sheet in this block. The BEP doesn't release serial ranges for the uncut sheet printings as they do for the circulation production, so we have to work it all out as we go. So this sheet helps to make the shape of this particular printing just a little clearer.... Thanks!
I think it would be quite cool to own a sheet of uncuts like that, no matter the series/year/denomination/etc
