Man, this just sucks for everyone involved - everyone has lost when something like this happens.  As an owner of several physicals every time I read something like this it sends a chill.

I hope the source is found, and that Alitin honors their pledge to offer refunds.  If you can find proof of when your coin was swept, and the value at that time, it is worth trying to go through something like renters or homeowners insurance and see what they say.  Sometimes you do need an extra rider on your policy to cover these things, sometimes not, depends but at least worth a try.

I know it won't really replace what was lost, but add me to the list of interested parties for any resale of these, peeled or still intact but de-funded.  PM me your asking price, for either series and/or multiple coins.
