my name's Gordon summers
[12]
I'm the chief engraver I have been at
[14]
the Royal Mint for about 20 years at the
[17]
Royal Mint we produce three types of
[19]
finish for commemorative coins bullion
[22]
brilliant uncirculated and our highest
[24]
quality finish proof these are processes
[28]
which have been refined and developed
[30]
over thousand years or more at the Royal
[32]
Mint our focus really is to produce the
[35]
highest quality coin no matter what the
[37]
finish is we always put a great deal of
[39]
craftsmanship and skill and knowledge
[40]
into every design and into every coin
[43]
it's difficult really to understand the
[45]
level of care that goes into our process
[48]
it's a lengthy process for whichever
[49]
final coin finish we produce we take as
[53]
much time and consideration on the
[54]
design and the development stage for
[56]
bullion brilliant uncirculated and proof
[59]
coins but where it diverges really is
[62]
the quality of the finish on the final
[63]
coin bullion is all about producing lots
[66]
of coin efficiently the brilliant
[69]
uncirculated part is really it's a
[71]
higher quality than our circulation
[73]
given an extra finish more handling in
[76]
terms of polishing and finishing and
[78]
then right the peak of our quality is
[81]
the proof coin where we spend a lot of
[82]
time both on the tools and in the
[84]
striking to make sure that they've
[85]
produced the highest quality coin that
[87]
we could possibly do I'm Toni Nelson I'm
[91]
a master tools maker and I've been
[93]
working at the Royal Mint now for 18
[95]
years no matter what the final finish is
[97]
it's our job to ensure the dyes are
[100]
sharp and accurate to make the finish on
[102]
the coin as close to the original design
[103]
as possible for the proof finish we'll
[107]
spend more time on the tools than for
[108]
other finishes often work in the detail
[111]
relief to allow action material the
[112]
additional polishing approved eyes i'm
[115]
just sharpen up the edges the material
[117]
you see how the edges just a little
[118]
rounded well this is where we just give
[120]
it a little tap tap to bring it back
[122]
perfectly sharp after every stage of the
[125]
tooling I would inspect the tool itself
[127]
making sure that the quality standards
[129]
maintained our master tools are at the
[131]
highest quality standard
[133]
no matter what the final finish might be
[135]
my name is David Woodward I am the
[138]
senior day polisher I've been at the
[141]
Royal Mint for 38 years we polished the
[145]
days that we use to straight the coins
[147]
to ensure the highest quality of finish
[150]
on the final coins for the bullion coins
[153]
the days are finished by a polishing
[156]
machine the brilliant uncirculated
[158]
unproved eyes are hand finished we use
[162]
six grades of diamond paste on different
[166]
woods from cherries to balsa to give the
[169]
dyes a perfect mirror finish the proof
[173]
finish has an extra stage the mirror
[175]
finish is protected using tip we use
[179]
fine sand and glass bead blasters on the
[182]
surface to add the frost in effect it
[185]
can take several hours to finish each
[188]
proof day which will then create three
[191]
to four hundred coins before having to
[194]
be repolished my name is Paul Barrington
[197]
I'm a set at the Royal Mint and I be
[199]
moved near for lamb use both brilliant
[202]
uncirculated and bullion coins a machine
[204]
fed bullion coins are struck once and we
[207]
produce up to 250 an hour brilliant
[211]
uncirculated coins I start twice on a
[214]
regular checks will videos around 100 an
[217]
hour a proof coins each plant is picked
[221]
up individually and a hand placed into
[223]
the press with cleaner dyes with air
[226]
before each strike to ensure maximum
[228]
detail they'll be struck after six times
[231]
using that pressure to preserve the fine
[233]
detail of the operator with the extra
[236]
key and attention will only produce on
[238]
50 proof coins on our the proof coin is
[241]
able to hide more detail clear relief
[245]
and a finer smoother service making the
[248]
very best of the original design every
[251]
coin is checked when they come off the
[253]
press to make sure that everything is
[255]
perfect the line up the diameter and the
[257]
quality of the coin if you're interested
[260]
in buying gold coin just for the value
[262]
of the gold then we'd recommend you go
[264]
for the bullion if you want something
[266]
that's ever higher
[267]
quality but available really to more
[269]
people the brilliant uncirculated but if
[271]
your focus is to have the highest
[273]
quality the most craftsmanship certainly
[275]
the proof coin would be the one to go to
