HUGE Rare 1800s to Current US Stamps Collection-Beautifully Displayed In Folder

This is a massive lifelong collection consisting of numerous pages of antique US stamps, ranges from the 1800’s until modern with many pages being fully filled or mostly filled! Price is Firm. I paid $850 for this about 10 years ago. Some rare stamps included! Please review pictures for full item physical condition, in older album with shelf wear such as loose pages. Valuable old US stamp collection, would be a great collectors item or investment.
