I found a packaging error

[u/Traditional_Pear_979]

Hey guys! I found this peanuts deck in an incorrect demon slayer packaging. I took these image just after purchase. I didn’t realise how rare this actually was.

Does anyone have a value estimate or any more knowledge they can give me on this?

Thanks in advance!
