Do you 'quarantine' your milky/toning modern coins?

[kimchi]

Just going through some bits and bobs and sorting out storage for the latest lot, and wondered if folk keep their milked/toning stuff separate from the rest, or try to?

I.e. do you feel it's 'contagious'?!! Or just best practice to store the more reliable silver away from the (potentially) milky stuff?

 Anti-tarnish and desiccant packs are of course used in my airtight secure storage locations, but was just wondering if folk here like to keep it separate, and if so if it's just a feeling or whether anyone's actually had some experience where they suspect milk's transferred.

Cheers!
