<p>[QUOTE=&quot;Paul_NL, post: 25531394, member: 108102&quot;]Hi guys, I’m puzzled by something, and hope to hear your thoughts on it.</p><p><br /></p><p>In the last the Leu Numismatik Web Auction, no. 30, that took place from 13 to 16 July 2024, there were several top quality copies of the well-known Tiberius Denarius from Lugdunum (the &#039;Tribute Penny&#039;). Some of these copies were clearly struck with identical dies, both obverse and reverse. For example lot <a href="https://leunumismatik.com/en/lot/50/1879" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://leunumismatik.com/en/lot/50/1879" rel="nofollow">1879</a> and <a href="https://leunumismatik.com/en/lot/50/1880" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://leunumismatik.com/en/lot/50/1880" rel="nofollow">1880</a>. And also lot <a href="https://leunumismatik.com/en/lot/50/1881" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://leunumismatik.com/en/lot/50/1881" rel="nofollow">1881</a> and <a href="https://leunumismatik.com/en/lot/50/1887" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://leunumismatik.com/en/lot/50/1887" rel="nofollow">1887</a>. Of these last two coins, the identical dies are easily recognized by the die break on the reverse. One of these, I managed to acquire.</p><p><br /></p><p>Now am I wrong to think that it’s quite rare to find ancient coins struck with identical dies? And is it even more rare to find these in one auction? Or does this happen more often?</p><p><br /></p><p>Now of course I have been studying the coin that I acquired, the one with the die break, and I was all the more surprised when I discovered that a month earlier, on June 25, 2024, again a similar, and thus third copy was sold in the Tauler &amp; Fau Selection Auction 145 as <a href="https://subastas.tauleryfau.com/en/lot/25062024-3821-3821/80-2893-roman-imperial" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://subastas.tauleryfau.com/en/lot/25062024-3821-3821/80-2893-roman-imperial" rel="nofollow">lot no. 80</a>. Clearly the same dies again. This one is graded by NGC.</p><p><br /></p><p>So again, does anyone have an idea whether it is common to come across multiple copies of ancient coins – in this case three – that are struck with similar dies? And when they come onto the market in such a short period of time, what can be the reason for that? A hoard find? A collection that’s being sold? If this would happen with, for example, Dutch 17th and 18th century coins, I would be alarmed and think of possible forgeries. But with these Tiberius coins I assume that several knowledgeable people, including NGC, have thoroughly looked at them. And also my own copy, looks authentic. So are there other explanations?</p><p><br /></p><p>Anyone have experience with this?</p><p><br /></p><p>I&#039;m really curious about your thoughts on this.[/QUOTE]</p><p><br /></p>
