This is already a feature.

Add some items to your collection on the site.  Then visit the set page to see your collection progress.  You can even filter the results to exclude variants (like reverse holo) and see how many of those cards you own.

You can see the collection progress at the top of any of the pages like this:

You can already search for anything in multiple sets.  A search like "Pikachu Pokemon" will bring up more than 200 cards from dozens of sets.

You can do that.  Here is an example with Charizard Reverse Holo as the search term.

The results are from all different sets.  

Let me know if I misunderstood the request.

Thanks for the feedback.  Prices on the marketplace are all in USD because you will receive payment in USD and the exact amount you get in your currency will depend on the exchange rate at the time.

I've fixed this game now.  I added a bunch of sales and the price has been adjusted.

Thank you

The cover artwork will be included on items by default when you add an item to your collection without a photo.  

You cannot export the images, but the images are shown for items in your collection when you view the collection on our website.

If I am misunderstanding the request, please let me know.

This seller had 6 copies of the system.  You can see in the title the "6", "5", "4", etc.  The prices are low because the seller listed multiple items to end at the same time.  The buyers divided their bidding.  They appear to be legitimate sales.  The seller just had multiple copies.  

Glad you found the option now. I'll look into the automatic options and see if that is something we want to implement for users or not and how we would do it.
