PriceCharting already excels at raw price data, collection tracking, wishlists, lot valuation, photo appraisal, and trends. However, many collectors especially those with large or growing collections across games, cards, Funko, LEGO, coins, etc. struggle with “what next?” and deeper analysis. Users frequently request better completion tracking, filters for standard retail releases, population, grading insights, and ways to make data actionable. This feature builds directly on existing strengths like collection tracker, trends, photo tools, API, and turns passive tracking into an active, engaging collector’s, companion boosting user retention, time on site, premium subscriptions (Pro), and community contributions, e.g. more data uploads.

Core Feature Details

• Completion Percentage & Smart Set Progress: For any console, set, series, or custom filter, e.g. NES RPGs, Pokemon Base Set, LEGO Star Wars, show % owned, visual progress bars, “missing” lists prioritized by value, rarity, demand, and estimated cost to complete, factoring current prices, shipping, condition. Expand on the existing % feature with dynamic subsets.

AI-Powered Recommendations:

1. “Based on your collection, heavy on SNES RPGs and modern Pokémon, here are undervalued titles trending up.”

2. “Similar collectors own these high ROI items.”

3. Integrate photo appraiser, Upload a shelf/box and get “add these missing pieces” suggestions.

4. Wishlist alerts, “Buy when price dips X% below trend.”

5. Portfolio Analytics Dashboard, Premium-heavy.

6. Total value over time with charts, inflation adjusted.

7. Performance by category/platform, e.g. “Your Nintendo holdings up 15% YoY”.

8. Risk/Opportunity flags, “This sealed game has low recent sales volume, consider selling?” or “High population in PSA 10 raw copies may be safer.”

9. Exportable reports like PDF/CSV, for insurance, taxes, or selling entire lots.

10. “What if” simulator, “If I grade these 5 games, projected value?”

11. Social/Community Layer, optional but sticky.

12. Anonymous compare to community benchmarks, e.g. “You’re in the top 20% for Switch completeness”.

13. Opt in friend sharing features for collections, wishlists already requested.

Implementation & Monetization Wins

1. Leverage Existing Data: Use current sales history, population reports, PSA, CGC, etc., big movers, and user uploaded photos.

2. Tech: Build on the photo AI and API. Start simple with rules based filters, then add ML for recs.

3. Premium Upsell: Free basic % and missing lists, advanced analytics, AI recs, alerts, and exports for Pro users.

4. Data Flywheel: Encourage more accurate user data entry conditions, purchases to improve site wide accuracy.

5. Mobile/App Boost: Perfect for the iOS/Android apps, quick shelf scan, suggestions.

Expected Impact

1. User Love: Solves real pain points like decision paralysis in big collections and “am I missing good deals?” Leading to higher engagement and positive reviews.

2. Business: More Pro conversions, affiliate sales via recs, API usage, and marketplace activity.

3. Differentiation: Stands out from basic price guides like eBay, PriceGuide apps by feeling like a personal collector’s advisor.  

4. Votable & Feasible: Ties into many existing requests completion %, filters, grading, trends. Easy to prototype and iterate based on votes.

This would make PriceCharting feel indispensable for serious and aspiring serious collectors. Post it on the feature requests page with a clear title, description, and mockup screenshots if possible, it’d likely get strong votes quickly! If you want, I can help refine the pitch or suggest variations, e.g. focus more on grading or international markets.

if i have a quantity of lets say 50 pikachus that i paid $50 for, and i sold 1 of them for $5.  I should be able to go into that and deduct 1 pikachu from the 50.  Instead i have to remove 1 from it, then add 1 on its own, then go and put in the sale.  Can this be optimized to allow 1 of the original position of 50 to be counted as sold?

Just as on Discogs, it would be a nice addition to PriceCharting to see how many users have a specific item added to their collection or wishlist.

Add support for these TCG / Wildlife cards

Please add SET " Pikachu Cosplay Halloween " to Other Cards Categorie

Request Change / Contact Admin from Item Interface

As a contributor who notices incorrect or outdated information, I want to be able to directly contact an admin or moderator from within an item page, so I can easily report issues and request corrections without needing to search for contact details manually.

Current Problem

At the moment, reporting incorrect item information is not intuitive. Contributors do not know:

• who the admins or moderators are,
• which contact method should be used,
• or which email address from the general “Contact Us” page is appropriate for item correction requests.

This creates unnecessary friction and discourages contributors from reporting mistakes.

Proposed Solution

Add a “Request Change” or “Send Message” button directly on each item page.

When clicked, the button should:

• open a modal or popup window,
• contain a textarea/input field for the contributor’s message,
• optionally include the item ID/title automatically,
• and send the request directly to admins/moderators responsible for reviewing content updates.

Benefits

• Makes reporting incorrect titles or metadata significantly easier
• Encourages community contributions and quality control
• Reduces confusion around who to contact
• Keeps contributors inside the interface instead of redirecting them externally
• Creates a more streamlined moderation workflow

Suggested UI Flow

1. User opens an item page
2. User clicks “Request Change”
3. Modal opens with:
   • short explanation text
   • textarea for the issue/request
   • submit button
4. Admin/moderator receives the request with linked item reference

Optional Improvements

• Add predefined categories such as:
  • Incorrect title
  • Wrong metadata
  • Duplicate item
  • Missing information
  • Other
• Allow users to track the status of submitted requests
• Show confirmation after submission

There should be a free game to play if you have an account and have Pokémon in your collection...
