Social Platform for Sports Card Collectors
Mantel
A social platform for sports card collectors featuring community posts, card trading, badge progression systems, and an integrated marketplace. Users showcase collections worth up to $18K+, trade PSA-graded cards from $22 to $16,531, earn fire badges for engagement milestones, and track market values with social media mentions.
Mantel brings sports card collectors together with a social-first approach. The platform combines Reddit-style community posts with eBay-style marketplace features, all wrapped in a warm cream and coral aesthetic with the signature script logo.
Community Feed & Card Posts
The feed showcases card posts from collectors like Carl Davidson (76 pts, 12 posts) and Sina Soujeh (164 pts). Each post features PSA/CGC-graded cards with titles like "Cristiano Ronaldo" or "All time legend," emoji reactions (thinking, fire, happy), sport tags (Soccer, Baseball, Football), and upvote counts. The sidebar filters by 10 sports categories.
Profile & Badge System
User profiles feature a sports art banner, favorite sports badges, bio, social links (Twitter/Instagram), and the signature fire badge progression system. Users earn badges at 1, 10, 100, and 1000 milestones across three tiers (orange, silver, red). Stats show total points (525 pts) and streak count (11 days).
Card Collections & Marketplace
The Collections tab displays 3 Cards worth $18,231 total with horizontal banner preview and "Add sport card" CTA. Cards show sport category badges (Soccer, Basketball), player name (Cristiano Ronaldo, Michael Jordan), PSA grade (10), type (Base, Refractor), year (2020, 1998), maker (Topps, Finest Mystery), and price ($22 to $16,531) with Buy buttons.
User Posts & Activity
The Posts tab on user profiles shows "3 posts" with time filters (All time dropdown). Each post card displays the graded card image, title (Zacian 36270), description ("Does anyone know this card?"), emoji reactions with counts, and interaction buttons (react, comment, share). Posts show "Soccar" tag and notification badges.
Search & Discover Cards
The Cards Finder lets users search across the platform with "On mantel" scope filter. Results show "3 Cards have been found" with grid/list view toggle. Each card displays: Name (N), Grade (G), Type (T), Year (Y), Maker (M), and Price ($). Cristiano Ronaldo search returns PSA 10 Base 2020 Topps $22, Base 2020 (no price), and PSA 9 Stickers signature 2006 $1960 with red Buy buttons.
Full Post View & Comments
The single post view shows Carl Davidson's "All time legend" post about Mike Trout with full description, emoji reactions (12/6/4/2), and 6 tags (Soccar, base card, Aregentina, Fc Barcelona, Chrome, Autographed). Features threaded comments with "7 Replies" expansion, inline rich text reply box (B/I/U/@/emoji), and nested @mentions like "@CarlDav I think it's not possible to do so".
Multi-Step Post Creation
Creating a post follows a 3-step wizard: Step 1 has Title and Body with rich text editor (B/I/U/@/emoji/list) and camera upload. Step 2 adds Main Topic (General dropdown), Sport selection with AI art thumbnails, tags (up to 5), and "I want to sell cards" checkbox. Step 3 (for sales) adds Player Name, Price ($$$), and Link fields. Progress dots show current step.
Card Info & Market Analytics
The card detail sidebar displays comprehensive data: Card Info (player, grade, type, year, maker, price), Player Profile (DOB, citizenship, position, current club, market value with achievements), Current Owner with ownership lineage, Market Value chart ($22 current to $62 high), and Social Media Mentions showing TikTok/Instagram unboxing videos.
