Yes.  Clicking "Show Historic Prices" link on any item detail page will show the price history for the game, card, comic, etc.

On desktop those price history charts show up automatically.  On mobile you have to click to make them visible.

Fixed now.  Thank you.

Thanks for this feedback.  

For now, search is the best way to find those.  If you search something like "SM244" or "XY178" that should bring up the correct card.  Or you can add "promo" into the search for example, "Aegislash 60 promo"

Thanks for this suggestion. The best way to do this now is to filter the set list.  For example, you can filter the NES page to remove hardware, variants, and only items released before a certain date.  Here is a link:

https://www.pricecharting.com/console/nes?sort=name&genre-name=&exclude-variants=true&exclude-hardware=true&when=before&release-date=1999-01-01&show-images=true&in-collection=

That should be only licensed stuff that came out originally and not homebrew or later releases.

Done.  Thank you

Added.

We have support for that set here:

We plan to add future Unlimited sets to the site as they come out too.

I don't understand this request.   Can you give me more info about what you are asking for?

Thank you.  Very interesting idea.  I'll think about this more and see how many people vote for it.  There might be some regulatory & legal issues involved in something like this.  I'm not sure.  I can see this being useful though.

This feature is available for Retailer subscribers along with some other profile page customization.  Good suggestion about opening it to all users though.
