Hey guys, Ludkins states that the package that is sent to them should be sufficiently insured with the insurance covering how much we paid for our cards. Now, from what I understand, this means I’ll also need a receipt of my purchase should my package get lost. - My cards are incredibly old, though, and I obviously do not know how much I have paid and also do not have a receipt. How does this influence my insurance cost, and how can I even prove how much the cards are worth in case they get lost?
@funmonkey54 works for them so he can help you with this.
I think they insure the cards for “market value” which means that the insurance will be dynamic, for example if your card gets a PSA 10 and gets lost during return you should be insured for more than if your card got a PSA 9 
There’s a contact tab on the website. You should use that if you have questions about the service specifically.
