ok but dont you know when something is struck with lots of pressure and when it strikes the planchet, and that whatever design is being created with the die............... dont think that with all that power and energy is going to stand still or not create anything.
The pressure & energy does create something.........that being the metal in the blank being compressed and flowing into the design on the dies.....the pressure & hold time is precisely controlled to allow the full design to be imparted to the blanks without causing any squeeze....so a coin is created from that pressure & energy.
" the blanks have again been hardened and must now be softened (heated) to controlled temperatures, approximately 1400 degrees Fahrenheit, changing their crystal structure to a softer state. The annealing ensures that the blanks have reached a coinable hardness so that they can be stuck to capture the full relief of the designs of the working dies. This process prolongs the life of the coining dies by ensuring well-struck coins with lower striking pressures. The blanks are then "frozen" into that state by a water quench bath"
The hardened die has a substantial amount of steel behind it, typically 3 inches, so I doubt any of the die design is transferred back to the press and even if that were to happen I doubt that any distortion would then be transferred back through another 3 inch die to the next coins being made on that press.
As to coin designers having guidelines to only produce designs which would hide all the previous designs struck on the press.....that would have to be one of the best keep secrets and would make the designing of new coins one of the most difficult tasks imaginable, if not outright impossible.
Sorry to be so negative.
EDIT
The softened blank absorbs the initial pressure by being distorted to match the designs on the dies. When it exactly matches the design on the dies the pressure is applied equally across both dies.The flat ends of each die having the pressure applied to them, which is now transmitted through the coin, the design on the coin has no effect on either flat end of the dies as the design on the coin exactly matches the design in the die.The design has no more effect than a flat blank between two flat dies would, there is no localized pressure points to cause press distortion. -

Every coin has new dies made, the press itself does not make the impression in the planchet but the pressure applied to hardened steel dies(which are changed for new ones when worn), see picture from http://www.coinnews.net/2013/04/03/u-s-mint-at-san-francisco-preparing-coin-blanks/
Notice the substantial amount of steel behind each & every die.
You might find this of interest.

I have looked at all your posts and have absolutely no clue what you are trying to 'teach' us to see

Happy Birthday Bill.

Very nice. There might be the reverse also in lead somewhere.
The first advertisement for this medal inviting readers to apply for specimens appeared on the 1st Nov. 1928. 2 sizes 76mm in gold(only one made), silver or bronze, 32mm in silver or bronze. Interestingly a number of requests were made for examples in other metals but no more information about that.

I have looked at all the images on the web that I can find, this is yours next to the Bargello's example http://www.palazzo-medici.it/mediateca/it/Scheda_Medaglia_della_Congiura_de_Pazzi
Notice yours has the wide band above the inscription, hence Lorenzo's head is not flattened, which runs almost all the way round the medal, the reverse is the same. Not one of the other medals has this band.
Someone might have produced a later copy as it does appear to be almost too good to be true and if the size is the same as the medals missing the band that could also be problematic. Also the hair edge is singularly different on your example(to all the others) and lines missing on the center panel. This makes me suspicious of it and believe it is a later copy.
Still very nice & one that I would happily have in my collection.

I stumbled upon this whilst looking for something else, cannot even remember buying it, must have been a few years back when I was having a lot of medical problems, I must have put it away and completely forgot about it. A slight improvement on the first example!I think it is dated 1726.

Forrer does not list this version, one was offered on eBay a month or so back, unfortunately I was outbid

I took the liberty of producing this to make it crystal clear. Pat

I wish you luck Art and look forward to seeing any of the photos.

My nominee would be BHM 2351 (from Atlas Numismatics' inventory).
I suspect that is a winner, could you count the words for us, just to be sure

Fauver, Alexander 1814-1fpa 25mm R-6 by Kettle. The copy/reducing lines are clearly visible, the cutter juddered going over the bust ribbon and some of the letters. The 'D' has a clear cutting line acrossed it. As is the case with these medals, that show the die still had machined marks, the piece is in great condition, being silvered-copper also makes it slightly rarer.
FAUVER ALEXANDER-2a R.-6
You might find this link of interest, it is a post of mine re the Kettle family of die-sinkers http://www.worldofcoins.eu/forum/index.php/topic,27159.0.html I still have a lot of pieces to add to that link.
Here are 4 more of Kettle's I still have to add to that post, the top one has central machine marks on the reverse, unlisted as silvered, unsigned and has the rarer obverse, "THEY" starts just above the exegue.
FAUVER PEACE 1814-3, ONLY LISTED IN COPPER R.-8(5-10 KNOWN) THIS BEING SILVERED IS EVEN RARER, MIGHT BE UNIQUE.
FAUVER PEACE 1814-2a R.-6
FAUVER Peace 1814-1 R.-6, ONLY LISTED IN BRASS, THIS IS HEAVILY GILDED SO RARER

IMHO they look to be modern fakes, & not very good ones, sorry.

I guess you know there is another medal with the same adverse, Bramsen 1447:
In post-Renaissance France, society ridiculed and humiliated husbands thought to be battered and/or dominated by their wives. In France, for instance, a "battered" husband was trotted around town riding a donkey backwards while holding its tail.
Great find, one which I was not aware of, I guess that you have seen this one of mine with the same German inscription.
If you ever consider selling or exchanging it, would you please let me know(PM me). Thanks.

3 on eBay here http://www.ebay.fr/sch/i.html?_odkw=lvd+XIIII&_sop=18&_mPrRngCbx=1&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X.TRS0&_nkw=%2CAeternae+Concordiae+Franciae+et+Hispaniae&_sacat=0 by another engraver.
Yous is a smaller version of the Louis XIV, Peace of the Pyrenees medal by HARDI or HARDY.
Seen here http://www.tantaluscoins.com/coins/23439.php & here http://www.vcoins.com/en/stores/coins_to_medals/37/product/1660_france__louis_xiiii_the_peace_of_the_pyrenees/336408/Default.aspx
I think the last price is way too high, yours might be a modern re-strike too.

I guess the L.T., in the exergue, lead to the supposition of it being a Doge Lorenzo Tiepolo's coin but the L.T. is the unknown mint masters initials.
Happy to help.

Nice medal! Do you have any others in the series?
No, I was not even aware of the series until I acquired this one, in fact it was not until I sent pictures to Philip Attwood at the British Museum asking for any info re this specific medal and he informed me of the series and that it had to be issued after 1546, when the Sacred Books and the Traditions of the Apostles were accepted.
He covered the series in his "Italian medals, c.1530-1600, in British public collections" so he was the right authority to ask.

Beautiful!
Nice to see the beautiful snow leopard back too

This is a view of trees across the Credit River close to my home, it being Thanksgiving Day in Canada yesterday many people were taking pictures.
Though it is a nice image, with my photography as with my medals I am a details fanatic. No one else seemed to notice what I did, barely visible in the lower right of the scene, beneath the green tree this side of the river, the trees in full fall colors opposite were being reflected in the water under the said tree. So climbing over a barrier and down a steep slope, where there was no path, I was able to capture this image. The circular ripples are just the icing on the cake of what, to me, turned out a spectacular shot. Well worth the climb.
I was so pleased with the picture that I returned about 2 hours later, with the sun very low & the light mellower, and captured this.
