<p>[QUOTE=&quot;rrdenarius, post: 2425786, member: 75525&quot;]The weight of an As varied by location (I am not sure if this is town or a larger area). I have seen weights, pre-devaluation, that range from 260 to 340 grams. I normally use 300 grams for cast bars and aes rude knowing the number varies with time and location.</p><p><br /></p><p>The Spink&#039;s Numismatic Circular in 1909 lists weight standards for Central Italy of:</p><ul> <li>Italian # = 400 grams</li> <li>Roman # = 327 grams</li> <li>Oscan # = 283 grams</li> <li>Umbria, Tuder # = 256 grams</li> </ul><p>FYI a link to the circular - </p><p><a href="https://books.google.com/books?id=y7M_AQAAMAAJ&amp;pg=RA1-PA203&amp;lpg=RA1-PA203&amp;dq=central+italy+weight+systems+pound&amp;source=bl&amp;ots=b1uiJUAbY6&amp;sig=qeLpYdfsi5sv37AzVtv6raDpoAA&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwjhi7uWsuvMAhWIVz4KHVe8B7EQ6AEIHDAA#v=onepage&amp;q=central%20italy%20weight%20systems%20pound&amp;f=false" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://books.google.com/books?id=y7M_AQAAMAAJ&amp;pg=RA1-PA203&amp;lpg=RA1-PA203&amp;dq=central+italy+weight+systems+pound&amp;source=bl&amp;ots=b1uiJUAbY6&amp;sig=qeLpYdfsi5sv37AzVtv6raDpoAA&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwjhi7uWsuvMAhWIVz4KHVe8B7EQ6AEIHDAA#v=onepage&amp;q=central%20italy%20weight%20systems%20pound&amp;f=false" rel="nofollow">https://books.google.com/books?id=y7M_AQAAMAAJ&amp;pg=RA1-PA203&amp;lpg=RA1-PA203&amp;dq=central+italy+weight+systems+pound&amp;source=bl&amp;ots=b1uiJUAbY6&amp;sig=qeLpYdfsi5sv37AzVtv6raDpoAA&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwjhi7uWsuvMAhWIVz4KHVe8B7EQ6AEIHDAA#v=onepage&amp;q=central italy weight systems pound&amp;f=false</a></p><p><br /></p><p>Vecchi in Italian Cast Coinage gives the weight standard of an As at the start of each section. The oldest first and more recent later. For example Rome was listed first:</p><ul> <li>280 - 250 BC, currency bars</li> <li>280 BC, Dioscuri / Mercury series, based on an As of 324 grams</li> <li>270 BC, Apollo / Apollo series, based on an As of 334 grams</li> <li>several other series until ...</li> <li>225 - 217 BC, Janus / Prow right, As of 270 g</li> <li>225 - 217 BC, Janus / Prow pelet series, As of 260 g<br /> </li> <li>235 - 217 BC, Janus / Prow left, As of 256 g<br /> </li> <li>217 - 215 BC, Janus / Prow semilibral series, As of 132 g<br /> </li> <li>215 - 212 BC, Janus / Prow post semilibral, As based on decending weight standards. I have a cast one of 60 grams.</li> <li>211 BC, Janus / prow struck series, I think these start about 50 grams and rarely a bit more. My largest is 48 grams.</li> </ul><p>[/QUOTE]</p><p><br /></p>
