Old Coin Checker
Prototype — Upload coin photo, detect year (<= 1980) and estimate price
Note: OCR tries to read year stamped on coin. Agar OCR fail kare, neeche manual input se year daal sakte hain.
Developer notes: Is prototype me Tesseract.js client-side OCR use kiya gaya hai — yeh sab cases me perfect nahi hoga. Production ke liye aapko coin image classification model + coin database + pricing API add karna padega.
