1932 Penny Thick Planchet Error
Thick & Thin Planchet Error
If coining strips are not rolled properly coins which are the wrong thickness are
produced. If too much pressure is used when rolling out the strip you can end up
with a planchet strip which is too thin. If too little pressure is used when rolling out
the strip you can end up with a planchet strip which is too thick. If the rollers are
out of alignment on one side, a tapered planchet is produced. This means you end
up with a planchet that is thicker on one side and thinner on the other.
