Top o' the day to ya Paddy my friend. Going all technical are ya now?
Pray tell can ye elaborate just a wee bit more then?

So for example, if you should try to take a Macro shot of a dime, what
has to be the same size?

You'd need to move the camera close enough to the dime - or vice versa - so
that the image of the dime appears as large on you sensor as it is in real
life.

In that particular case it would probably overlap at the top and bottom
since the sensor is rectangular.

A macro lens would support that and would be able to focus even though it
wouldn't be a whole dime in your picture.

I have an icon on my Sony that shows macro?

Simply having the macro switch on doesn't mean everything you shoot in that
mode is a true macro photograph.

For instance I had my macro lens on when I shot that raindrop but it isn't a
macro photo. The lens has macro capability but I did not utilize that
capability because I didn't get close enough.

And if I had all I would have had was a picture of a drop. It might have
been a less interesting photograph.
