i was thinking of insuring mine also but im now thinning my collection so will have to see what happens
as for the value of yours for insurance purposes....... absolutely no frikin idea but i should imagine a pretty tidy sum

like you say you have a rough monetary value but the stuff you have is another level mate !!!
some of the regular vinyl, cd's etc wont really have a value due to the availability but the rarer stuff i would estimate roughly and then double the value for insurance purposes - value should increase also due to the hall of fame induction.
i recently sold a couple of passes and boots on ebay which more than doubled my estimate, this could be down to the current tour or induction, but as you know the market changes all the time depending on newbie buyers that pay over the odds and bidding wars etc.
have a look at completed listings on ebay and try to work an average for each item, or just have a look on eil maybe
i appreciate most of your collection is now very hard to find if not harder so it would be difficult to estimate
good luck though
