You photograph an item — coin, collectible, piece of jewelry, vintage items, even antiques, anything — and TurnOver runs it through multiple AI vision models simultaneously. Each one analyzes the image independently and our "vision to value" process returns an identification and estimated value range. Those results get compared and synthesized into a single response with expanding detail.
Because no single model gets it right every time. Each AI agent was trained differently, compresses knowledge differently, and has different blind spots. Where one model's knowledge is thin, another's is often solid. The consensus signal is meaningfully more reliable than any individual result. It's the same reason you'd ask four experienced dealers instead of one. Second opinions often have value; even human professionals may make mistakes!
No — and anything that tells you otherwise is lying to you. TurnOver gives you ranges based on comparable sales data and AI analysis. The actual price you'll get depends on platform, condition, timing, and whether the right buyer happens to be looking that day. We give you an honest estimate, not false precision.
For common items with deep market data — popular coin series, well-documented collectibles, widely traded vintage goods — very accurate. For rare, niche, or one-of-a-kind items, the range gets wider because the data gets thinner. TurnOver explicitly offers confidence rating. Additionally, quality images diminish efficient evaluation, potentially less accuracy. Multiple images compound to improve assessment, up to 5 images per item analysis.
For sure. See our guide in the app or at turnover86.com about image quality. The models are only as good as what you give them to look at.
Coins and currency, jewelry, vintage collectibles, trading cards, sports memorabilia, antiques, estate items — anything with a resale market. Quality of the image is crucial to accurate determination, we allow additional photos may further enhance appraisals. The app is optimized for the recommerce world: items you found, inherited, or accumulated that you're trying to understand and potentially sell. (Note we offer a guide to better quality images.)
Glad you asked: We will be upfront on limitations. First multiple items in same image defy assessment. Separating objects is possible yet it remains unclear which object you have in mind. Second, closed containers and boxes — if we can't see the item, we're evaluating the container. Unique or extremely rare items also present challenge when lacking data on comparable sales. Items where condition determines value often a photo doesn't show the details that matter. In those cases TurnOver will tell you the confidence is low rather than pretend otherwise. It's technology, not magic.
