[QUOTE="GriffonK, post: 3209878, member: 98447"]From 1901 through to 1938 for KM#29 20 R the metal used was nickel and the weight was 4.00 gram, 21mm. In 1938 KM# 29a the alloy was changed.1938 to present day the alloy is noted as copper-nickel. With a weight of 4.20 gram. 21mm. So in the transition of the alloy and the changing of the weight. Is it possible this plays a roll in the variety I bring to your attention. As complete novice I naturally dont have the understanding of the process or sequence of events that lead to doubled and tripled die coins. Thanks.[/QUOTE]
