<p>[QUOTE=&quot;Valentinian, post: 2850141, member: 44316&quot;]A &quot;double strike&quot; is not the same as an &quot;overstrike&quot;. <i>Overstrike</i> refers to a new type struck on a flan that was a coin of an older type. We had a thread on those:</p><p><a href="https://www.cointalk.com/threads/byzantine-overstrikes.302645/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/byzantine-overstrikes.302645/">https://www.cointalk.com/threads/byzantine-overstrikes.302645/</a></p><p><br /></p><p><i>Doublestrike</i> refers to a coin struck with the same dies twice, with different enough position so you can see both strikes. A <i>flip double strike</i> is one in which the two strikes have the obverse struck on the reverse and vice versa. The coin must have come off the dies, been judged to need a second try, and accidentally put back with the reverse to be struck by the obverse die.</p><p><br /></p><p>This coin is even more complex. It is a triple flip strike. I think I can explain it as a single type (Justin, DO 9. Sear 63) where the large &quot;M&quot; has a star to the left and a cross to the right with obverse legend DN IVSTI - NVS PP AVG.</p><p>The coin is large: 31-29 mm and 15.17 grams. Interpretation of the strikes is informed by the usual 6:00 die axis of Byzantine copper.</p><p><br /></p><p><br /></p><p>[ATTACH=full]676240[/ATTACH] </p><p>This is one orientation. See the &quot;NVS PP AVG&quot; from 1:30 to 4:30? Then the bust should be upright and you can see some of it--head, clothing on the bust, but all weak. Using the 6:00 die axis, the other side is right-side up, so it had a large &quot;M&quot; with a cross to the right and &quot;..ON&quot; (of &quot;CON&quot;) in exergue, officina A between the legs of the M.</p><p><br /></p><p>The &quot;STI&quot; at 7:00 on the reverse is best understood with the coin rotated and sides flipped.</p><p><br /></p><p>Here is a second orientation:</p><p>[ATTACH=full]676241[/ATTACH]</p><p>See the &quot;STI&quot; at 10:00- 11:00? And, again the &quot;ST&quot; part is visible on the obvious very off-center strike with more of the obverse legend: [DN]IVST .&nbsp; Now, knowing that the &quot;STI&quot; was at 10:30, I can see the top of the head (just above the left leg of the &quot;M&quot;) which is why in the first orientation the symbol on the left side of the reverse M is obscure. But in this orientation you can see it on the reverse: a clear six-pointed star and mintmark &quot;CON&quot;. You can see bits of the cross to the right and the cross above the M.</p><p><br /></p><p>So, this coin was struck three times and they never got it right. Once as in the first picture. Once as in the second picture, well-centered. And once as in the second picture, left side, very off-centered. (With the coin in hand I can&#039;t identify anything remaining from the other side of that off-center strike). Because of its sharp edge which obliterates the top of the M, I interpret the very off-center strike as the last of the three. As the aphorism has it, &quot;If at first you don&#039;t succeed, try two more times and then give up&quot; (aphorism slightly modified from its original form.)</p><p><br /></p><p>Tell me that Byzantine copper coins are not beautiful!</p><p><br /></p><p>Can you show us any doublestrikes?[/QUOTE]</p><p><br /></p>
