This is something that we probably should be noting or announcing from time to time, for the benefit of the newer members and guests.

As with any valuables, if you have a growing collection, or some pricey pieces, remember to secure them (and your house in general).... and as always, be careful who you let into your house if you don't yet know them, even if they appear to be a fellow fan. Until you trust someone who has access to your house, always secure and watch over your valuables - toys or not.

A couple years ago there was a news report about a Superman collector in America who let someone into his home, but didn't realise he was just scoping the joint to rob later.
It doesn't even have to be someone claiming to be a toy collector either, as TV shows like Toy Hunters is educating non-fans into the potential value of vintage toys that people here are collecting. If something is small and publicly known to be valuable, toys, jewellery, electronics or cash, they become a target... so...
- Document everything you own,
- Secure it,
- Restrict or Supervise Access, and
- Insure it.

As the catch phrase goes - Be Alert, But Not Alarmed.
So don't be worrying that your collection is now at risk, but do take the normal precautions you would with anything of value in your home.
And if you need to meet up with someone new who is buying or selling, prefer meeting at their place or somewhere neutral, or if they do come to your house, keep an eye on them like you would do with any stranger.
