Amazing start to the collection! You have a great variety so far. It’s always great to see non-TCG items.
Here are some useful guides if you want to go in the deep end for cameos and variants:
Non-TCG is also its own craziness, but I see you’ve dipped your toe in already! There are tons of non-TCG items to collect (probably an endless amount), so if you want to ask away, there are collectors here that have pretty good knowledge in non-TCG items.
Hope to see more of your collection in the future!
