In this video, I experiment with cleaning, polishing, and blackening custom deep-engraved brass coins—something I’ve never tried before. Using the Monport GA60 MOPA Fiber Laser, I engraved several all-brass coin blanks with detailed designs, then tested a variety of post-processing techniques to bring out the best in each one. From wire wheels and Brasso to dremel polishing and blackening agents, I walk through each step, share what worked (and what didn’t), and compare the final results. Whether you're into metal engraving, coin customization, or just love watching a good transformation, this video is packed with insights. Full coin blank links and laser details are in the description below!
