I gave myself the New Year's resolution to better organize and track my collection. Originally, I had a (very out of date) google sheet to track all my things but I wanted something that looked nicer and made it easier to find and sort through my items (without having to put in all the effort of formulas). I was able to find a Notion template which I then modified to fit my needs. Here are some screenshots of v1 which has a clean way to navigate by team, category, and sport, and a simple UI to enter new items as they get added to my collection. Feel free to make any suggestions on ways I could improve it or what you guys use to keep track of your collections.

Hi all! New here to Mantel and excited to begin this journey. Wanted to share a bit about Mascot for those who haven't heard of us. Mascot is the leading inventory management and multi-sales channel platform for collectibles. We're best known for the ability to list items for sale across many marketplaces including eBay, MySlabs, MyCardPost, Veriswap, TikTok Shop and Shopify - unlimited, for free. We also partnered with PSA, BGS, SGC, CGC and TAG where we pull all details of graded collectibles just by entering a serial number. We also have partnerships with big trade shows such as Burbank Card Show, Dallas Card Show, The Philly Show and more where dealers can upload items available for sale and collectors can search for inventory available at the show. Plus, much more to come!
