Saved Me Time & $$

This app is amazing, before I paid to get cards graded I knew the value and then made a call to grade or not!!! But, the best was it helped me get my collection valued and found out if it where stolen or destroyed I would have been underinsured and devastated!!!!
Thank you “Slabline” 🙏🙏🙏🙏

Finally know what the collection is worth

I scanned the QR label on a graded card and it pulled up the card and its live value instantly — no typing, no searching. Added the rest of the collection in a few minutes and now I can see what everything is worth in one place. The coverage gap tool was an eye-opener; we had way more value sitting on a shelf than our insurance covers. Clean app, no clutter, does exactly what it says.
