I think the biggest criteria is if it is appealing. Second is price, third is rarity, and fourth would be sentimental value.
I have four favorite pieces, for different reasons. I have a 10oz "Sparkle bar" that has crystals and sparkles in the bar itself. It's one-of-a-kind and I'll never sell it.
I have a 2022 5oz Reverse Proof Libertad that is expensive, low mintage, and has silver boobs. 😆
I have a graded end-of-roll Morgan that is amazingly toned. It is shades of blue, green, red, purple and orange, and is amazing to look at.
Lastly, I have a custom-poured silver reproduction of the old Blue-Eyes White Dragon Yu-Gi-Oh card from the Kaiba starter deck I played with as a teen.
They're all favorites for different reasons, and I doubt I'd sell any of them except maybe the Reverse Proof Libertad, and that's if I got a good price for it.
I hope that's not as clear as mud. 😆
