Would each coin represent a separate 'bin' or would the random selection of a coin plus the ten flips represent the randomized selection condition for c_rand?

Trying to understand if it's necessary for the coins to be identical.
Interesting question indeed. Hoeffding does apply to each randomly selected coin individually as you point out. If the coins have different values of E_{\rm out}, then the added randomization due to the selection of a coin affects the relationship between E_{\rm in} and E_{\rm out}. This is exactly the premise of the complete bin model analysis.
