Feedback Help with weathered Kisekae Plate No.024 Wooden Mario for New Nintendo 3DS

[SrMininez]

So, I bought online this beautiful plates that I wanted since I was a lil kiddo, but I couldn't help to notice that it's slightly weathered, specifically on the top plate. Specifically Bullet Bill, Mario's hand and the middle of the coin are almost undistinguishable from the background (the pictures have more contrast so it isn't as noticable as irl) Is there any way to make it sharp again? Thanks in advance

Is that real wood? If so, there's several options like trying to match the stain color and using a fine tip brush to touch it up. You could also use a brown sharpie to do it, which might actually work on plastic as well if there's a decent texture to it. I'd also use a matte clear coat on it after you're happy with the results.
