Stamps (Philately)/Need Help Mark.


The last time you told me to go to library to look up prices.  I am 70 years old and I am donatinf all my philatelic holdings.
I do not have the time to research these stamps.  I just need a rough value of an honest guess so I can donate to the APS.  I have already send them thousans worth.  Also Spellman Museum, AFDCS.

Just give me your best guess Mark.  I need to send them out soon.  Does that .90 cent look like #166 (A54) #191.  

Anything else on this sheet of value.  Please do not tell me to look them up sir.

Thanks for your help


I can't positively identify several of the stamps without direct examination because of the subtle differences between certain issues.  But I can venture a guess of about $1,000 catalog (retail) value for the undamaged stamps in your photo.
