5.7 grams/ 87.5 grains is the normal weight.
I can't see anything from the scan that leads me to any particular cause why
you can't see any copper core, except if the coin has been lightly plated, as
a novelty item, or out of boredom by someone at a machine shop, or someplace
that plates items.
Yes, the coin could be plated, and still weigh that amount....also, it's possible
that your scale is off by one tenth of a gram........
It could be something else too, but it can't be determined based only on the scans....
Just my opinion......

That being said, it's more than likely that the edge has been plated. I've seen a number of such alterations over the years.
If you want a definitive test, take a scalpel and shave off the metal from one side of one of the reeds while observing the procedure under a microscope. Invasive yes, but it's simple, cheap, and yields unambiguous results.
