These are clearly not originals.
It's normal.
I remeber at the time people selling Fish Disks and other collections and they get very few few money only for the copy something like contribution.
And nothing bad because every Amiga Magazine toke advantage spreding Public Domain.
Me and a friend of mine had bought almost 300 fish disks but now they are not good anymore and just for collection we have found an FTP hosting about 1000 Fish Disks!
