The Mint states that, with normal wear and tear, the colour should remain for a number of years, although this claim was quickly disproved . The colouration compounds are attached to the metal on a specially prepared 'dimpled' section of the coin, and seem to come off easily if deliberately rubbed. The coin will retain its full value even if the red poppy has worn off or been removed; however it is now expected that fully coloured specimens will become collectible in the future.
