Quadrum Intercept caps

[Silvergun]

Has anyone got any thoughts on the Quadrum intercept caps , are they worth the extra cost , are they any better than the standard Quadrum caps ?

As far as I can tell it's the black foam that's different. Protects against tarnishing.

It might make sense for modern proof silver coins but they usually come already in their own capsule. The only silver I have that I would prefer not to tarnish are pandas and lunar series but I prefer to keep those in original capsules.

I use Quadrum caps mostly for gold where I guess the regular ones are just as good.
