What is the Kause # number that is given? I can think of different types of '5 centimes'.
The 3 over 2 production is a small part of the overall 1863 production.
Something like 100,000 coins are typically struck off a die pair. In a total production of 16 million coins, something like 160 die pairs would have been used.
How many 1862 dies would have modified to produce '3 over 2' dies is unknown.
My guess is that as little as only one die may have been modified, or as many as just a few may have been modified. That implies that approximately from 100,000 to x00,000 coins would have been produced.
Relative scarcity and demand of the '3 over 2' variety can only be judged by Krause's pricing.
