Vintage Taxco shadow box style sterling silver brooch

Vintage Taxco brooch. Has a mark on the front that seems to be from when it was made since it goes through the silver. Might be able to polish it and be less obvious but it is grooved. Still a very nice piece and collectable. Has some surface scratches and patina. Enclosure is a strong, secure and the pin is straight. Could be reimagined, used/worn as is or polished up to shine bright. Please see photos for the best description thank you. Stamped Taxco sterling eagle 3 mark and a B comes with box and gift pouch
