<p>[QUOTE=&quot;Conder101, post: 1233426, member: 66&quot;]Beef is wrong.&nbsp; There are no examples of doubled dies from hub doubling in the early or middle dates that I know of.&nbsp; There are some in the late dates.&nbsp; In the 1820&#039;s and early 30&#039;s machine doubling was quite common because frankly the presses were wearing out.&nbsp; Once they switched to the new steam presses in 1836 most of the machine doubling disappeared for awhile.&nbsp; Until 1836 the dies were still produced by hand punching except for the central device which was punched in using a screwpress rather than a punch and hammer.&nbsp; If they had to use the screwpress more than once with an annealing in between pressings then a doubled die would be possible, but I don&#039;t know if they ever did a multiple pressing and as I said I don&#039;t know of any doubled dies in the early or middle dates.[/QUOTE]</p><p><br /></p>
