so over the weekend I was able to pick up a couple of these from a coin show and a lower premium than there current value.. They have box and COA, Not sure as to whether or not I shoul send them in at a chance for PF-70 or just keep them in the original packaging.. Anyone here had luck at getting a 70 on the proof eagles? BTW, this is the lowest mintage of all the Platinum eagles "excluding the burnished platinum eagles" so it is considered a key date
