Dad died - left ridiculously huge stamp collection - wondering the best way to determine value.
Before he died he told us to sell these stamps. I'm serious, there's over 2,000 stamps, mostly loose, some on envelopes, some on a series of envelopes, some in books, some in official book series (i.e. United Nations). It's just so much and my family has appointed me to sell it all to raise money for my mom.
I'm just wondering what would be the most easiest and cost efficient way to determine the value of these stamps. Are there certain rares I should be looking out for? Can I just go by year (for example, like everything from 2004 is 70-90 cents?) I know I might sound confusing but I'm really not trying to look up 2,000 stamps, but maybe if there was a good book I could buy, I would do that. But googling each stamp, most likely having to go to ebay, and then click and search the sold auctions for each stamp is just too tedious.
Please, if you guys have any recommendations, I would really really appreciate it. Thanks!
