In 1923 two values from the fur collar postage stamp issue were overprinted to service stamps but never issued. This was 3 cent green and 17½ cent ultramarine and brown. Later the batch of not issued service stamps were overprinted to postage stamps again with an uprated value and issued in December 1923. The values were 10 cent on 3 cent and 1 GLD (Guilder) on 17½ cent.
From the 1GLD on 17½ cent a forgery is recoded from which both overprints are applied on a genuine basic stamp.
