@Shaggy_Bets Congrats! I recommend this book... I hate reading books, but this is only one page per day, and I've found a ton of great advice here. I'm on my second year of rereading it.
@SGP_Vick Beautiful cards... I would definitely get them out of the screw cases, because over time they tend to pinch the corners flatter than the rest of the card, and if you grade them they might get denied claiming "altered stock".
