I found airtight capsules exactly right for the Criptoe Guldencoin. You need to make the hole in the rubber a little bit bigger, but than you'll have an pretty show and protective case.
I want to order them, but maybe there are more peeps in the NLG community who want one.
It's €2,50 per capsule, I wish to ship them all to my address and from there distibute them further. In order to keep the price as low as possible, the more the marrier
