Unused cards in original packaging are the most desirable and hold the highest value.
In 2026, many cards, particularly standard British Telecom (BT) cards, have plummeted in value, sometimes trading at only 10% of their 1990s catalogue price, or around 80-95% lower than final published rates.
Cards featuring specific art, advertisements, celebrities, or limited-run promotional designs are sought after.
