In addition to uploading pictures of the case and manuals, also integrate 3D models, viewable in-website if possible 

For the base set Pokemon booster packs, separate the packs based off the Charizard, Venusaur, and Blastoise pack arts. The Charizard is worth much more than the other two and throws off the values. 

Since some collections are quite valuable, they are a useful part of the net worth to consider for some people. This would make it useful to add external API usage by financial trackers like Monarch Money, so that transactions (collection additions/subtractions) and balances over time can be viewed.

Many store would pay to save time for creating item plus it would help the sync

If you have a video game which is currently set as follows:

Folder: A

Cost: 0

Total Value: 100

You then edit this item, add a cost of 25 and move to folder B (as part of the same edit), the record looks to be updated correctly, however, the cost summary for folder B shows:

Value: 100

Cost: 50

It looks like it doubles up the cost in the summary (not the record) when you move folders and change the cost price at the same time.

I have reproduced this with both the inline grid edit as well as the full record edit.
