Metal Tray

does anyone know what is this tray for? it measures 20 x 16 cm.
it has some numbers on the back that seem been handwritten 9559 SRS 1 what may they mean??
is it old or has any value? thanksss

It looks old. I don’t think the number lets we know the age of this tray. Maybe it stand for the number of the tray when it produced. is it silver tray?

thanks for your answer, it is not silver, it is chromed

a pin tray maybe? Something along the lines of that. Coins? Letters? Household items in general
