Yes, this is a never used tag. As a general rule, we never get used tags.
As this is an imported car, my Buick Marquette came to Finland from America
in 2008, it obviously didn't have a tag before. On previously registered cars,
you may get the old tags back.
Pics:
The Buick with it's post 1972 licence plates.
Six digits. Also the new plates since about the year 2000 have a blue
extension that says FI and EU. I cut that off, it's just too ugly on an
old car. (criminal behaviour)

And in the second pic the
Essex, which had its original tag on new plates, since it had been sold
new in Finland. Same style, but I painted the outer border black to make
for an older look, that border line came in in the fifties, I think.
Also not allowed, but luckily mischief no one cares much about.
