Help Needed With 1976 Innsbruck Olymp. Souvenir Sheet

Can someone help me with the CV of these 2 Hungarian souvenir sheets?
One is with perforation and the other without. There is the number on the upper part of each sheet, if this is indeed the number of the sheet, the umperforated one might be a scarce copy. It has only 4 digits. Or, it might just be my fantasy

You remind me my huge Olympics collection I sold years ago. This sheet is Scott #2401 and value is $3.25 mnh and $3.00 used in Scott 2007. There is no mention of the imperforate sheet value. I would say double the value but surely less than $10

Monsieur Timbres,
Thank you! What surprises me is that if the other sheet is not so rare and not so valuable, why Scott failed to mentioned it?... Remains a mystery. Maybe it is listed in other catalog then.

Not sure if this is relevant, but one of the serious exhibitors at my stamp club has one exhibit about space exploration (one particular mission I think, don't remember exactly as it has been some time since he had his presentation of the exhibit). He did mention that the space stamps he had without the perforation could be quite difficult to obtain, and could be a bit pricey. I have no idea if this translates to this sheet or unperforated stamps from Eastern Europe in general, and I have picked up unperforated Olympic stamps from Eastern Europe without paying that much for it.

So a lot of typing without any conclusion it seems.
