insurance value

I accidentally let my collector insurance lapse this winter, now I am trying to get new collector insurance and am wondering what value I should put on it. It is a 67 Dart GT convertible, rebuilt 273 2 barrel, automatic, bucket seat with console, no rust through, some paint flaws, scratchs on glass, 97,000 miles. Top could stand to be replaced. I looked on Hagerty and they list this condition as $13,500, to me that sounds high and I am thinking more $10,000. Whats your thoughts. Should get a new appraisel, (old one done 20 years ago, listed it at $8,000 to $8,500) but am in a hurry to get it backon the road.
Thanks
Aaron
