Uncatalogued BT Phonecards

The BT Phonecards shown below are all unique in the fact that they don't appear in either the UK 1 BT optical card catalogue or the UK 2 BT chip card catalogue.

Some of the telephone cards shown below have previously unknown or unlisted batch and control numbers, others are unofficial overprints, while some have never been seen before.

Pictured above: A 5th series 100unit definitive BT Phonecard with the unofficial overprint wording "with the Compliments of Century 21 Designs" in the bottom left hand corner of the card.

What's a unofficial overprint? An unofficial overprint is a card that has been overprinted by a private individual or company and has not been produced by the phone card manufacturer e.g. Landis & Gyr to advertise a product and/or service.

Please note: When the UK catalogues were produced it was not their policy to catalogue privately overprinted cards.

Do you have an uncatalogued BT Phonecard that does appear in any UK catalogue and isn't pictured below? If you do, please email a scan, so I can add it to this page and share it with other collectors.
