Yeh but as you have stated many times... you bought direct from containers, cash in hand to make deals and so got all your machines at a reduced rate.
What you paid and what Joe Bloggs will pay are 2 different entities.
Insurance companies will squirm every which way to avoid a payout ( most will, not all) and then only give you about 80% of what you valued them at, unless of course you have written evaluations with a current date.
Always add 1/3rd of price for insurance purposes
