Amazing how a simple question can get expanded into a not so simple question. All of the above...

1) Someone buys a chip on eBay for $30 and it's insured and shipped, and lost or broken. You get $30 that's it.

2) You own a chip that cost you $XYZ and it has a value of $5000. You insure it for $5000 and ship it. It gets lost or broken. You get $5000.

In the first case you have a sales slip and record of the transaction.

You will need to prove the value, in the second case, not just your opinion that it's worth $5000.

One small example: I have some product that I purchased for $100 and I sell to customers for $200. I put it in a box and ship it off UPS. It never gets there, so I file a claim. UPS pays MY COST not the value.
