You obviously have the stamp images. Put them someplace easy to get to on your computer (such as your desktop), with simple names such as 557.jpg and 557a.jpg.

Your stamp is perf 10x10, Scott 586. Even more common than an 11x11 Scott 557. Since it is hinged, poorly centered and has perf problems, it's not worth more than face value. Use it as postage on a piece of outgoing mail.
You don't have to take my word for it. You can still get it certified. Don't go through APS, you will have to spend $37 on a membership, plus their cert fee. Go to PSE or PSAG and they can assess your stamp, but remember to submit it as a 586, not a 557c, so you will pay the minmum cert fee.
