I am requesting the ability to set a "sold" price for items within my collection. When viewing the collection summary, sold value/total should be shown as a separate column and not calculated into the overall value of my collection, since I no longer own the item. This feature would greatly assist in managing my current collection and separating those cards that I have sold and no longer own, but still want to have a history of the item and its metadata.

Pokémon cards were released in many different languages. We should be able to distinguish these either with a language selection in the card details or (preferred) a new group for “Pokémon Base Set Spanish”.

I'm not sure how these sales are being pulled in, but every single loose sale listed is incorrect and for different variants. None of those should be attached to the N64 (generic black) console. There are many other games and accessories that have the same exact issue. I would encourage this to be looked into.

Add pricing for like Movie Trading Cards, Cartoon Trading Cards, you could even add the Old school Desert Strom Cards, 

For example, let's say you have 6 same charizard cards but you want to keep only 1 and sell the other 5 with all your other duplicates. You can select to move 5 of them to a different folder so when you want to see all the duplicates at once it doesn't include the 1 you wish to keep for yourself.

Hi! I'm hoping that this feature will be added to see the most or least expensive thing you've bought. It would be very useful for me, especially for finding which comic I didn't price at all. Thank you for considering, and sorry if I posted this incorrectly!

When I sell a game locally and not on PriceCharting, I have to remove the item from my collection.

It would be really helpful if I could keep the data of said sold game for future reference.

I have been thinking about a list of same as the Collection, with all the previously filled details of the item (even editable?), especially with the date of removal, price bought and sold.

It would be helpful when buying to see how long it has been since a seller last logged in to know if your purchase would be shipped out in a timely manner.

You could provide a drop down menu on the bulk load screen for a comic collection which would allow list to be loaded to a folder rather than 'not in a folder'

I would like a button or another mechanism to improve QOL for adding duplicates to my collection. Right now I have to right-click on the orange "in Collection" button, open in new tab, increase the quantity, or click the add another copy button at the top and then refresh and close the tab to go back to the main list. I do the new tab so as to not lose my place in the list as I'm cataloging a stack of duplicates in numerical order. Please inform me if there is a better more efficient workflow for this already that I am missing, I only started using this site about a week ago. Loving it so far!! Great work!
