importa self-adhesive coinholders
« on: April 07, 2021, 07:16:48 PM »
i had stored a plastic token in an importa self-adhesive coinholder.
when i opened the coinholder again, the inkt of the coin remained in the coin holder.

i thought these were safe for plastic  tokens...

should i use other coinholders?

Very much in general:
  • Plastic is safe in just about any coin holder, celluloid is unsafe in any of them. See here.
  • Some paints on top of the plastic come off easily, others don't.
I keep all non-metallic items in plastic coin cabinet drawers, brand name SAFE, making sure they get "dry" air ventilation and check the drawers regularly and I still had some problems.

They were overshadowed by problems with the supplier. The original Dutch importer, Van Mastricht did OK only as long as I withdrew what I bought from the shop. When I ordered by mail, he took the money, never delivered anything and stonewalled attempts to communicate. He sold his business to Europost Breda. The mercurial owner of this company accused me of being threatening when I wanted to make peace with him and told me he intended to help when he was being threatening. Meanwhile, the German company did nothing. Don't say I didn't warn you.
