Grey Sheet subscribers-- What should I pay for these common AU Morgans?

I'm buying two 1900-P dollars, one 1925 Peace, and one 1922-S Peace for my daughter's and my type folders. The seller told me to pay them whatever the going rate is.
Since I haven't subscribed to the Grey Sheet in over 3 years, I have little idea what the going rate is for the coins in AU53 to 55.
In a related note, I'm thinking of buying a roll of common date Buffalo nickels in G to VG to hand out to my daughter's class. How much do these run?

When in doubt, check Ebay for prices realized, or buy prices in ads in the backs of the magazines, for common circulated items.
Writing that, I have the 9/5 Numismatic News. It shows Covina Coin paying 80 cents for full date Buffalos, 45 cents for partial dates, $13.75 for AU Morgans, $13 for AU Peace dollars. Covina usually has among the highest offers around. I don't know how many coins they reject or downgrade to the next price lower, so I'll stand by the prices I put in the previous paragraph. Also silver was about $1 an ounce higher when their ad probably went to press.
