What insurance company does this? The typical certificate tells you that they will pay you "the lesser of: (a) the cash value (original cash value less depreciation) as determined by the Company or (b) the cost of replacement."

Most travel insurance (over)sells the product with flowery language that leaves to the reader's imagination, but the fine print is what you get. Plus the fact that at least 60% of your premium goes to profits, selling commissions, and other non-insurance benefits items.


OP: if your mom paid for the ticket by credit card, you should check with the issuer if she was insured, but don't expect replacement value from it either.

OP: can you get a copy of the submitted receipts from the customs entity, under a freedom of information or access to personal data framework request? Also, does the receipt you got from customs itemize the value of the declared items? That could be the proof you need.
