Hey, I'm pretty new and have recently made a few purchases of the new Harry Potter sets. I got 10 of the new Chocolate Frog Tiles but unfortunately got doubles of Newt Scamander and Gold Dumbledore, I was just wondering what people are thinking of doing with their doubles; Keep them? MOCs? Sell them on another site like Brick Link? Nice to meet you all btw :)
