Are any of these stamps worth more than their face values?

I recently inherited this stamp collection from my grandfather, and am wondering if any of them are worth more than their face value?

If you think any are worth more but are unsure of the price, I don't mind researching those specific stamps individually.

Any help would be appreciated!

The greatest value for 98% of the stamps pictured is to lick them and stick them onto envelopes or packages to be mailed. The reality is these stamps can be bought in huge quantities for as low as 40-50% of face value, anywhere and all the time, especially at stamp auctions, or on ebay.

 

Greetings from Houston,
I use to collect U.S. plate blocks & can honestly say IMHO I can't see much in the collection worth more than 'Face', although, perhaps the Airmail blocks & Liberty Flag strips do have some value.
If you are looking to sell, have you considered placing the collection on eBay, as is? Or better yet, why not expand the collection and begin collecting U.S. Stamps? Good Luck whichever way you go.
Just my 2¢,

Thanks Don & Hochstrasse,
It's always nice to hear you have not completely 'lost it' @ the 74 yrs. mark.
LOL!
