You currently have bright on one side of the box and comparative dim on the other side of the box. That makes it difficult to even find a correct bounding box to be able to isolate the box to have a chance to do threshold detection to find the letters. The specular reflections of the gold also make it difficult. I think better illumination would reduce the problems.

You need better image capture conditions, such as alignment and lighting. Then do a background correction. Then look at the Computer Vision System Toolbox, which has OCR capabilities. https://www.mathworks.com/help/vision/ref/ocr.html#bt548t1-2_1
