Batch Item Attribution Assignment, Grade/Folder

A way to select multiple items in the collection and change Grade and/or folder. I use PriceCharting to determine which cards in my collection are worth grading, the two main folders I sort into are, "worth grading" and "cost effective". The difference being "cost effective" are cards whose value at the low end is above the price of grading and "worth grading" are cards whose value at the low end might be even or below the price of grading but at the high end command prices above $100. So it's nice to be able to change items from ungraded to a grade that corresponds with an anticipated grade then refresh the page to see the updated values. But I have a rather extensive collection so it becomes very tedious when I want to do this to a large number of cards. Otherwise I absolutely love this site, y'all had image search on desktop before ebay did and now you've got an app too!

I've had the idea for a digital marketplace where there is no general browsing of items but as a buyer you go to when looking for something specific and you search for that item and are only then shown all of the current instances of that item currently listed on the platform. So as a seller with an item that you know is valuable to someone out there you can list the item with description and condition just like an ebay listing. There would be a toggle for "open/not open to negotiations" and a minimum offer amount when "open" is selected. Buyers pay shipping and when the shipping method is selected a label is made available to seller to either print at home or QR code for the post office, no separate fee for the label that the seller pays for out of money provided by the buyer or however TF ebays "buyer pays shipping" works, all you see is the label created after the buyer has selected and paid for their preferred shipping method. I also think there should be a membership fee of $5 per month for the buyers to deter or inconvenience scalpers. You could function on like the AdBlock model where it's the $5 minimum but if members like and want to help support they can set a higher monthly amount. The Idea is if you are looking for a specific item and are willing to pay a premium for that item you are able to find a balance between condition and price point regardless of your economic ability. For example you'd accept an item in less than mint condition but still willing to pay that premium due to rarity or nostalgia. Oh, and no seller fee's either. I know, "well how does it make money?" well, it doesn't or at least not much. That $5 member fee granting access to an "exclusive collectors market" would probably barely cover sever and domain costs and might not even be tenable. The reason why there's no fee for the sellers is because it should be friendly to those who are needing to liquidate personal property assets that have value to a very specific customer base, and it is important that they be able to extract the highest possible return from the sale of that asset. It's a marketplace for Collectors not Investors.

Salute Comrades! Love everything y'all are doing here. If you can make my collectors market idea workable and it does make money, just give me a job or something :D
