True, Stampman2002, but then there's always the "Take a little; leave a lot" kind of thief who has somehow learned what you have and takes ONLY a few, high-value items, leaving everything else untouched. It could be quite some time before you notice something is missing, especially with 45,000 stamps.

Coin collectors have been victims of this type pf theft for decades.
It doesn't pay to advertise your holdings, especially on social media. There could be a dishonest stamp collector out there looking to score a particular item.
