very nice pictures #4 is my favorite

I am looking at portraits and taking close up photos of various collectable items coins and jewelery that I have acquired over the years

I am looking to get a macro lens for my Nikon d3300 that I will also be able to is when I upgrade my camera to the d500. Not sure which one I should be looking at 40mm, 60mm, or 105mm.
I am new to this site been shooting for 25 years mostly sports action and events. Just an amateur photographer would like to experiment with macro lens.
