I have a ton of swirls to go through. Is there anything in particular I should look for as far as what is collectible/valuable and what is not? The majority I am seeing are white based two-color (if white counts as a color). I also have quite a few transparent based swirls which I hear are pretty difficult to ID.
I think I'm making progress in IDing patches, ribbons, etc., but swirls I really haven't touch on and still have A LOT to learn. As always, I appreciate any tips/help/advice.
