Through negotiation, Emilio has received from dishonest payees two checks with the following histories:

(a) The drawer issued a check to the payee for $9. The payee cleverly altered the numeral amount on the check from $9 to $90 and the written word from "nine" to "ninety."

(b) The drawer issued a check to the payee without filling in the amount. The drawer authorized the payee to fill in the amount for no more than $90. The payee filled in the amount of $900.

Discuss whether Emilio, by giving value to the payees, can qualify as a holder in due course of these checks.
