It's hard when a good chunk of your collection was accumulated during your childhood. I got Apeface and Snapdragon MISB as Xmas gifts in 1987... I'm guessing my mum paid $20-30 for them... but I don't know for sure. Thunderwing was a bday gift in 1989 - I have no idea how much he costed. I bought the Pretender Monsters from Kmart for a couple of bucks each MOSC when they came out... but they'd cost a small fortune to replace in that condition now!

So as the bank told me, it's not at all about how much you paid to obtain the toys, but how much it would cost to replace it. Look at say car insurance -- it's like say car insurance, you can either insure it for the cost of replacement, or at its market value. I don't think car insurance covers you for its original retail cost, since cars are a depreciating investment. Same with say house insurance -- they don't insure you for the market value of the house, but the cost of rebuilding it. To my understanding, property insurance is about the cost of replacing the insured property (hence why they might insure a car for its market value, but not a house - because the cost of rebuilding a house might be quite different to the cost of selling it).

I'm not an expert on insurance, but that's how it was explained to me by an issuer at a bank.
