My condolences…Might I suggest your Dads friends? I know one of my most prized firearms came from the collection of a good friend. And a good friend of your Dads would be less liable to lowball on the price. Best of luck to you on this
You could always contact me or my father In law. We run a very well known auction house up here in northern Indiana. We have an FFL and do all the transfers here in house. We are both licensed appraisers as well. We have 5-6 gun auctions a year and have great success. Current market value at auction would more than likely yield you the best all around values. You get a check at the end and all are sold that day.
Thanks
Jesse
