I applaud you for your collection and the decision to have it all on display (I wish I had the space to display all my stuff!). I assume you allow interested parties to see your collection? It would be a shame to keep it all hidden away, especially as it sounds like a real nice group.
There's a need for collectors to be discreet when speaking about fellow collectors treasures as these things have greatly increased in value over the last decade or so. I always ask the owner before speaking about his/her collection to other folks.
