I have a set too! I have to find the kilt though
And the helmet too, unfortunately - unless you have it stashed away somewhere :/
As far as value...good question. There's a very small community of collectors who go after stuff like this, as they don't pop up for sale that often.
That said, I'd pay 100M or so for something like this to add to my collection.
If you have any complete [Exceptional] or Sewn suits, I'd pay at least ten times that.
