Major electronics retailer D Company announced in May 2026 the permanent establishment of "Digital Old Coin Classes" for senior coin collectors at 50 locations nationwide. Taught by retired engineers from camera and scanner manufacturers, the hands-on sessions cover scanning techniques, organization, and digital archiving for coin collections, held twice monthly. With a target of 10,000 monthly participants, the initiative is drawing attention from the old coin industry as a bridge between traditional collecting culture and digital technology.
