COUNTERSTAMPING TRADE SECRET (NOT REVEALED)
Dick Johnson writes: "Medal makers have been using
punches to place dates, names, other lettering, on existing
medals for hundreds of years. They all face the problem
of mashing the detail on the opposite side of the item being
punched, as will occur when the piece is laid on some hard
surface. (Something in physics about ?an equal and opposite
reaction? I suppose.) The suggestion in last week?s E-Sylum,
of using hard woods, oak, iron wood, ebony, are just not
realistic.Every medal manufacture has a thick piece of ..............
in which he places the item to be punched to add custom
lettering if this has to be done by punches (instead of, say,
inscribing with a motorized engraver or engraved with a
burin). ............. is sturdy enough to hold the piece
intact while the blow is imparted to the punch to sink into
the surface of the piece, yet this material is resilient enough
to ?give? and not damage the piece on the opposite side
(at the contraposition location).This is one trade secret I refuse to reveal. I?m just not
going to tell you what ........... is. I personally dislike
unauthorized counterstamping on coins, medals, tokens,
whatever. Yes, I know this was done in areas of the
world where coins were scarce and counterstamping
was done to identify pieces for use in local areas. That
was in the far past. Today we have enough mints
around the world to strike coins for circulation without need
for usurping another country?s coins by counterstamping.
Or irrationally punching your own country?s coins.I will reveal this, however. For creating repousé a thin
copper sheet is laid on a tub of tar and pitchblend. It is
tapped with a punch to form a design. This is the nearest
thing to ........... being used in modern times.Since The E-Sylum goes on the world wide web, I don?t
want this secret to get in the hands of hundreds of
schoolboys who get their mitts on a punch or two and add
their own brand of graffiti on any coins or medals. (Okay,
you juvenile delinquents, go get a tub of tar and pitchblend
and punch away. You didn?t learn about it from me.)"- 2004-08-15
