<p>[QUOTE=&quot;rrdenarius, post: 2406938, member: 75525&quot;]An interesting coin arrived today. From Kunker&#039;s web page, I could see what looked like an over-strike. In hand I am not sure what I have. It could be an over-strike from an earlier issue or a double strike of this coin. From the picture, I thought it might be a die clash, but I do not see it that way in hand. Look at the pics and let me know what you think.</p><p>[ATTACH=full]496811[/ATTACH] </p><p>[ATTACH=full]496812[/ATTACH] </p><p>I can not tell what I see from 9 to 12 on the edge of the obverse. There is an arc of impressions in the face also. </p><p>[ATTACH=full]496813[/ATTACH] </p><p>There is definitely a second row of border dots from 1 - 2. The lighter features at 4 are higher than the darker spots. Could this be from the tips of the helmet wings? Parts of the reverse have unusual step changes in height of the features (chest of left rider). It looks a bit like it could be a flip over double strike.</p><p><br /></p><p>Roman Republican Denarius</p><p>Mint&nbsp; Rome&nbsp; Crawford says Rome; Grueber says Central Italy; Sydenham says Rome and other</p><p>Issued by C.PLVTI, Caius Plutius, moneyer</p><p>Mint Date 121 BC</p><p>Weight 3.92, mine</p><p>I found lots more than 38 examples, but stopped writing and averaged the numbers. </p><p>Weight - max 3.94 grams</p><p>Weight - min 3.24</p><p>Weight - avg 3.82</p><p>Weight - st dev 0.130</p><p>Number 38</p><p>Diameter - max 19.2 mm</p><p>Diameter - min 18.3</p><p>Diameter - max&nbsp; 19.9</p><p>Diameter - min 17.0</p><p>Diameter - avg 18.1</p><p>Diameter - st dev 0.72</p><p>Metal AR</p><p>Serrated N</p><p>Cr&nbsp; 278 / 1</p><p>BMCRR Itly 454 - 460</p><p>Sear: #, VF, EF 153</p><p>Bab Plutia 1</p><p>CRR 410 / 414 based on helmet style</p><p>CRI</p><p>NMWar 451 451 - 455</p><p>NMCr</p><p>Orientation 11</p><p>Orientation</p><p>Purchased from <img src="https://www.cointalk.com/file:///C:/Users/Gene/AppData/Local/Temp/msohtmlclip1/01/clip_image005.png" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>Kunker</p><p>Purchase date 4/5/2016</p><p>Price </p><p>Currency&nbsp; Euro</p><p>Excahange rate</p><p>Grade gVF</p><p>Grade VF</p><p>Centering well centered</p><p>Strike good strike, over another coin?
