What is the ruling on buying and selling a gold ounce that has the image of a girl whose features may be unclear?

There is no objection to buying and selling gold ounces, even if there is an engraving on them, because the images on them fall under the category of images that are treated disrespectfully and whose use is not forbidden. Also, these images are not intended; what is intended is the gold, and the image itself is not clearly defined, and this is something that has become widespread.
