IDDD position on Peg-legs by Thomas Kalantzis.
IDDD position on Peg legs and why? Early on the mint had realized a problem with San Francisco Working dies, a critical flaw in design, early on the mint was dealing with dies braking up so fast a fix was needed, till a fix was realized a repair was needed, the Working hubs were abraded and then used in the hubbing process to make Working dies, notice all the 1971 high relief proofs and at least one low relief San Francisco die where abraded, the first experimental fix application to create peg legs for 1971 S dies, all show the left side (Bottom left serif) of the R removed and the right side changing from die to die, that is possible because each first fix Working hub was abraded separately from left to right, the Working dies are abraded as needed and is one reason they do not look alike, another is the Working die itself gets abraded and more changes occur to the Working die depending on the amount of abrasion the die receives, abrading was done to both Working hub and the Working die.. Take a look at the pictures of the peg legs below, any peg leg that has no leg serif is due to heavy die abrasion, the peg leg itself is hub and die abrasion event.
The second hub fix used on, to date, one die for Philadelphia and Denver in 1971 and 1972, this time tooled on both sides of the foot of the R in liberty, both serif tips are cut off making the leg look straight or square, then the process of hubbing the new die begins, the new working die is then abraded as needed.
1972 Proof, by this time the mint should have received the new die steel, did the new die steel do the job? if so then why did the mint change the distance between the Rs foot and the head?
It seems even though new steel was incorporated the mint chose to change the design, with a straight or square foot and more space between the the foot and the head.
The critical Flaw in design
The mint realized they had an issue after production started and demand an issue.
The critical Flaw hub side. Lets think in terms of reality, first a hub looks just like the coins we collect, with the lettering, design and the date standing high above the field on the coins planchet (The coin itself) on the hub side we see the R in liberty very close to the head and a very thin open space between them, think of it as the spaces we see between IN GOD WE TRUST with each letter having a space between them, what is the implication, doe's it effect the hubbing process NO, could this effect the working die? YES.
The Die side of the critical flaw
The critical Flaw die side. This time we need to look at this opposite of the hub, the working die used to make the coin is incused interesting when we read, the letters are always dark so to highlight the letters themselves, think about it, it is how we read and how we see things as interpreted eye to brain, now lets read the Working die exactly opposite of what the eye is used to.
The dies letters and head and date are incused high point is the top of the head, the die has two deep points very close to each other, the R in liberty (The foot) and the head are in very close proximity to each other, with a very thin piece of die steel between them (The Flaw) also the the foot of the R has very sharp points on each side and are level to and consensual to each other creating a short but sharp pressure point on the die, one point to the other, add the pressure the die receives as the coins are struck causes the dies flaw to interact with the pressure of the blow from the hammer producing early die failure in the form of die's cracking up with the cracks always going in the same direction as the serifs on the R east to west or west to east but never north and south, the cracking normally seen on the head below the R or on the fields left or right of the R in Liberty.. The dies where designed to produce X amount of coins per die anything less would have to be made up by further production using more working dies to make up for the shortfall.. Abrading the hub and the die the answer.
The 1971-S FS-401 low relief was abraded the same as the high relief proofs as was done to the well-known Wexler Die WDDO-007 and Wiles DDO-009, IDDD has it listed as IDDDO-8A.
There is a third 1971 S peg leg, we believe straight peg leg is another yet another method of abrading the R in liberty, this time both serifs where abraded on each side as well as the top of the leg creating a more square leg and both serifs even, this was another experiment the mint used to create a square peg leg, there are four known low relief dies to date with this experimental straight peg leg, one die for 1971 S, one die for 1971 D, one die for 1972 P and one for 1972 D, the one known 1971 S straight leg is listed as IDDDO+V-118.
IDDD believes straight leg, peg legs, are experimental in nature (The second fix) and the shape being the precursor for all 1972 S and beyond peg legs.
By 1972 a change was made for 1972 S proofs, a design peg leg is finally made and continued.
Further up-dates are to this process are possible and will be added as realized.

Notice the above R in liberty has been abraded heavy on the die to the point some of the R at the bottom has been abraded out
The R below looks a little different, it was abraded less this time on the Working die resulting in yet another peg-leg and again somewhat different then the above R, the reason is this die was abraded less on the Working die then the above Working die was treated, why, more then likely a secondary issue arose possibly the dies clashed or some other problem.
Note, both R are peg-legs indicating the hubs are in fact abraded first then again on the Working die as needed, all die's are before put to use are abraded and polished.
The pictures above are of the high peg leg variety, the two pictures below the first are of the same coin also has clipped planchet by Brian Vaile.
