Solution 1
If the number of pennies in the 26 canisters are 1,2,3,4,5...26. (Every number from 1-26 is included and is only used once)Then measure them all and plug in the numbers (Too easy....Hmmm)

Solution 2
Totally Random Number of Pennies
Measure them out, Find the 2 that are the closest in weight. Subtract the heavier one to the lighter one, Bing!!! The weight of the Penny

Solution 3
CHEAT
Measure out a penny now. A canister would probably count as the weight of 2 pennys, 3 if you have the cap on.

wow... solution 2 sounds like the one to me. solution 3 could be possible, hah he just said do whatever it takes to get the answer, except for copying off your friends lol. But yeah I might have ended up thinking of that after recording the data... but not before lol. thankS!
