If this is a PC card that you would like to display and protect, even with the ink stamp, a suggestion could be to use on of the "low end" cheap mass grading companies (ie GMA or the like for $2) just to have it in a slab. Some companies have slab only options also. If you were looking to flip or don't want the display option then I wouldn't.
