Unless I'm reading this wrong regarding cancelled checks, this is from the IRS website (Publication 17):

"Contributions of Less Than $250
For each cash contribution that is less than $250, you must keep one of the following items.

A canceled check, or a legible and readable account statement that shows:

If payment was by check: the check number, amount, date posted, and to whom paid.

If payment was by electronic funds transfer: the amount, date posted, and to whom paid.

If payment was charged to a credit card: the amount, transaction date, and to whom paid.

A receipt (or a letter or other written communication) from the charitable organization showing the name of the organization, the date of the contribution, and the amount of the contribution.

Other reliable written records that include the information described in (2). Records may be considered reliable if they were made at or near the time of the contribution, and were regularly kept by you, or if, in the case of small donations, you have emblems, buttons, or other tokens that are regularly given to persons making small cash contributions."
