Sorting by coin diameter

If feature to sort by coin diameter can be introduced for collections, it will be great help when I'm ordering coin storage supplies.

I don't think there is much merit for something like this in the catalog search as it is predominantly for finding stuff.
 

If you have a type collection you could use a range of diameters paired with the “in your collection” filters to get a number for your supply estimation. 

Or if you have year collections you can export your collection (with the right data boxes ticked) and use a tabulator program of your choice to find out what things to order.

P.S. because we no longer have the diameter but size (width, height) you also have to be aware of non round objects that obviously have a larger diameter then one side.

I didn't try out the filter for my collection search. It's indeed what I wanted. Thank you for guiding!
