Thanks for the suggestion.  You can't filter by keyword now, but you can filter out variants (not for resale and limited editions) and you can filter out region too.

You choose those options in the search filters box on every search result page.  You can filter to any particular region and remove variants from all results.  This choice sticks with you on future searches too so you will never see those items again.

Here is an example with no filter:

Here it is with the filtering to only NTSC without variants.

https://www.pricecharting.com/search-products?q=mario+party&type=prices&sort=name&console-uid=®ion-name=ntsc&exclude-variants=true

You  can filter by a particular set in order to see if you have a card for that particular set.  

You can search the site for a card and see the "blue" vs "orange" buttons next to each item that indicate if you own it already.  That is best method to see if you own a card or if it is missing.  You can click the "orange" button and it will take you to that card in your collection too.

This would work for finding all "pikachu" cards.  Or you can browse the set pages to see if you have every card in that set (and track your completion % too).  

In terms of seeing duplicates, there is not a good way to do that on the site right now.  I'll think about that some more.

Where would you like this ability?  In your collection or search results or somewhere else?

Can you give me an example of when you would want to use this option?  This helps me to understand the problem and see if this is the best solution.

Thanks for that feedback.  I'll look into this more. It might be easier to streamline the photo submission tool a bit to make that faster, but a scanner could be possible too.

So this would be like the photo tool we have now but streamlined because you would just scan the photo automatically and determine the card instead of needing to submit the photo?

I have a developer looking into ways to improve this tool.  It works well for most users, so I'm sorry you don't have success with it.  These intermittent errors can be tricky to troubleshoot.

We don't really authenticate items.  That is the job of a grading service.  We will let users know if they are selling a fake card, but error authentication is not something we specialize in at all.

Cool idea.  I can see that value in that for older items.  I'll have to see how popular this is before doing any work on it because it would take quite a bit of development and resources to store all of those images.  But it could be valuable too.

We used to track DVD prices years ago, but it was not popular.  We closed it down.

We are hoping to implement "folders" for this.  You can move items to a particular folder to organize them more if you want.  You will be able to name the folders too, "sell", "bad condition", "needs manual", what you want.

Do you think that would work for you?
