I always kept my negatives, but you are probably right. Those casts
had a purpose and were not needed after their purpose was fulfilled. I was thinking that these casts would have been treated like dies that were finished with their run of production (I guess I am thinking mostly of modern
medal and commercial token dies). But, I guess companies kept dies in case they ever needed them again. And with casts, there was no further need unless they auctioned the same coin again and that was so
rare an occurrence there was no need to keep them. I am just thinking aloud here, it is strange we never see casts, so most must have been thrown away.
