Domains with PR 5, 4 and 3 but no backlinks??

Hello!
Im just starting my own blog network, today I've found two PR5 domains and eleven PR4 also, just checked with sb and online tools and the PR are there but when I use ahrefs it shows some of that high pr domain has zero backlinks. All I think its the links arent found by ahrefs, anyone has experienced somethink like this before?
Regards

If the pr 5 with 0 backlinks? The PR is fake..

Try to type this on google. info:domain.com

it would probably show different domain.
