I have five Debden Sets to be listed in the near future. They are the earlier ones. The truth is that very few of these five Sets exist any more as so many have been broken up to sell the notes singly. A complete Debden Set with more than one note is now becoming rare. The C106 in particular is a Set that appears bur infrequently at auction. In my opinion, Debdens are so collectible and the way the notes are presented is so attractive. All were Limited Editions so have a look out for them when they are listed.
