Sorry for the late reply but I was driving back from Virginia...
Couple of things I want to point out.
A) I think I have a pretty good idea of what the clubs in my bag are worth :-)
B) While if I priced them all out brand new with tax at Golftown they might be worth a few grand, I could replace them in a day off Ebay and various websites for a fraction of that.
C) Given the above, I would be a complete idiot to make a claim such as that with my insurance company and thereby possibly pay thousands of dollars in increased premiums over the next 10 years, plus potentially jeopardize my ability to obtain insurance in the future should I ever have even one other minor claim.
D) Mint condition means never been played. 20 year old copper Eye 2s which are in the club storage are obviously being used regularly and are no longer mint. Otherwise why would they be in club storage and not a display rack in your basement? Average selling price for Eye 2 coppers in used but very good condition on Ebay is well under 300 bucks. See the below link:

E) You had 3 sets of irons etc. in club storage?!! Were you playing all 3 regularly? If not, why were they all there and what club allows you that much space in their storage? Or were these 3 separate sets belonging to 3 people and therefore 3 separate insurance claims of under $3000 each? $3000 of clubs I can find used and in excellent condition for well under a grand.
I'm sorry, but an $8,000 claim from clubs in storage will have an insurance company claims investigator visiting you personally to investigate such a claim.
Call me a dink if you like but those are my honest opinions. I'm really sorry you lost your clubs but if you make an insurance claim for that amount you are eventually going to pay every penny of that $8,000 and more out to your insurance company.
If you want send me a list of what you have lost and I would be more than happy to help you find replacements at a reasonable cost.
