Finally starting to figuar this out

Well, it's been a couple a months now. I been a paid member since December. I'm on my fourth submission. Once again, believing that I know how to "pre-grade" those coins. Probably, only to be brought back down to earth again to the reality of bodybags, and lower grades than anticipated. Coins that I thought would grade high come back lower, low ones come back higher than expected. I sit here with my head spinning. I've had huge disapointments with my first submission, but as I am learning, sometimes the failure is in the understanding of how to submit. Of course, the excitment is always there. Checking to see what they graded at, checking the mail, and most of all, just getting those babies into my hands low grade and all. It's like Christmas! So, once the calm sets in. Coins are put away. I play around with my registry sets abit. Then, WHAM!! It hits me again. I scan around on my desk, start digging into my collection, and lord and behold, what do I come up with? A whole new batch of "stuff" to send in again. Thus starting the rotation all over. Now, I'm waiting for Christmas in March!
