Good suggestion.  Thank you.  You can get pretty close with the existing filters.

https://www.pricecharting.com/console/nes?sort=name&genre-name=&exclude-variants=true&exclude-hardware=true&when=before&release-date=1996-01-01

Exclude variants, exclude hardware, and limit results to before 1996 (for NES)

That would still include some unlicensed items like Panesian games and Nintendo World Championships but vast majority of the list is licensed.

Like the opening response says.  This is a feature.  You just need to filter by Category first (video games, pokemon cards, etc) then you can filter by console.

That should already be the behavior.  After you refresh the results the total number of results does update unless the result count is still higher than the limit we show on search results.

Here is a result for "Mario Party" with 62 results.

I filter by console = "Gamecube" and the result is 5

Please let me know if I am misunderstanding the question.

You can filter by Console, you cannot sort by Console.

To filter:

Filter by Category first (video games, pokemon cards, etc)

Filter by Console/Set

This makes sense.  I'm not sure where to find accurate info on this.  Most games come out for the same prices each generation.  For example, almost every Switch game is $59.99.  For modern games this data is easy to record and compile, but I'm not sure about the historic items.

Please report those specific errors here or email them so we can correct it.  

With the [Holo] and "regular" cards, there should not be both versions unless there are two versions of the card, a holo and a non-holo.  We definitely want to correct that if it is incorrect for a particular card.

We have that whole set on the site here:

Prices will be added soon.

I've added [Stamped] versions for all of these now.

All of these error sales should be removed when we see them now.  Please give me a link to a card that has some of these sales and I will remove them.  Thank you
