Nico Nico Nii!~
The ones from the unlimited print run shouldn't have any checkmarks at all. A picture would help me identify those. As for the ones you have already, are those 1st edition?
1st Edition Shining Celebi can fetch anywhere between $50 and $100 by itself, and far more than that if it's PSA graded, so I think the lot you're looking at is worth it.
$45 to $65.

There will be more but just these for now
I can't price them if you don't provide sets for these. 90% of these cards share similar traits with another card, and I can't guess the sets they're from just with the collector's number level, and HP. I need the actual set name for most of these.
I can price Ho-Oh LEGEND's bottom half for you, though, as there's only one possible card that could be. That would be $4 to $7.
