Frequently Asked Questions
How do I track sealed product investments?▾

Are sealed boxes a good investment?▾
Sealed hobby boxes have historically appreciated well, especially products 3-5+ years old with strong rookie classes. Key factors: the quality of the rookie class (e.g., 2018-19 Prizm Basketball with Luka/Trae), print run scarcity (limited production runs appreciate faster), and brand prestige (Topps Chrome, Prizm, and Bowman Chrome are the top appreciating brands). However, recent overprinting has reduced returns on many modern products. Diversify across sports and years.
Which sealed products appreciate the most?▾
Historically, hobby boxes outperform retail and blaster boxes for long-term appreciation. The top performers are flagship products with strong rookie classes: Topps Chrome (MLB), Panini Prizm (NBA/NFL), Bowman Chrome (MLB prospects), and Upper Deck Series 1 (NHL). Products from 2016-2020 have seen the strongest gains, with some doubling or tripling in value. ETBs and blasters can also appreciate but generally at slower rates.
How should I store sealed products?▾
Store sealed products in a cool (65-75°F), dry environment with low humidity (40-50%). Avoid basements (moisture), attics (heat fluctuation), and direct sunlight (fading). Keep boxes in their original shrink wrap — opened but unsealed boxes lose 20-40% of their investment value. For high-value cases, consider plastic storage bins with silica gel packets. Stack carefully to avoid crushing bottom boxes.
Is my portfolio data stored securely?▾
Your portfolio data is stored locally in your browser using localStorage. It never leaves your device and is not sent to any server. This means your data is private, but it also means clearing your browser data will remove your portfolio. We recommend periodically screenshotting your analytics for backup.
