We have a thread somewhere regarding insuring our collections here.... not very adept at finding it in search but Im sure somebody here could post a link eventually 
I know what you mean,
I kept my Spreadsheet list up to date when I was starting coz of excitement - G1 and all that alone is a bit too much, then I have separate sheets for every other line, but after the 1000s mark, nay the 800s I just couldnt be bothered anymore. Ive included it in the insurance for my contents with NRMA but admittedly it underinsured as I dint get it properly assessed at the time I applied, it has grown exponentially since. We really should try and get a good valuer and prolly some insurer specializing in things like these - or antique insurers - I wonder at times when I watch Bargain hunt or Antiques roadshow - they often recommend an insurance price for an item and makes me think - who are these insurers and where can I get in contact with them - Australian equivalent. Coz yeah G1 alone is gonna be pricey....
