Looks like die polishing weakened these devices. Note they are in the die clash area?    Note on the opposite side of the design, the IN, Liberty is also affected. So it looks like another rescue die to remove clash marks from the die. (weakening the design features) Edited by coop

In your title you put re-engraving, this took my attention. In fact in 70's very few Master Die Hubs was re-engraved. In the 70's they use what we say recycling Dies by re-punched with the Master Working Die. Was a complex process of Die metal preparation, etc. So in those years we has the most Hub Doubling then any other period. The Mint Report of 1981 to the Congress address this issue and with the new horizontal presses installed and change in metals composition they was more efficient in quality and production.
PS.: Please do not tell me Mr. or Dr., because I hate this, I am simply Silvio. ( I was born to die and From earth I come in the earth I will return)

you are welcome, I'm glad could help, but what did I do?
On this coin, as Coop states, possible polishing to recover from a clash.

When something is engraved on a die, it makes an incuse mark into the die. But on the coins, it will show up as a raised areas on the coins when die engraving happens:  Polishing reduces the fields, removing the sub devices, that are slightly below the fields. That is what you are seeing on this bowtie. So if the area was engraved, then that area would appear raised. (Note the arrows on the above image) CoopHome: What does re-engraving look like on a die? raised areas on the design. die polishing reduces the clarity of the devices by removing them Edited by coop

chgk1628, I've watched this thread go on long enough without replying. I'm not sure why the 1971 re-engraving was not shown in pics or given a link to it but it would appear you know as much as most, that it exists, yours is not one of them though. It would appear that yours is as coop explained, an over polished ODV-027. Here is link to the ODV listings to compare yours and my 1971 D, that is a re-engraved cent. They happened in the P, D and S mints that year. Rare in just the obverse for San Fran and Extra Rare if you matched it with the RDV-008 reverse. By the way, your mm is MMS-008, not 007.

@MAKECENTS: Do you want to kill me with this sky hypothesis of re-engraved an S coin after 1965? First for your knowledge: The San Francisco Mint do not have the facility to rework or produce Dies. All are done in Denver from 1965. 1965 till 1969 some was done in Phil but after NO. San Francisco can re-polish but not more. I have no idea from where you take those information's which for me seem to be only some busting false tools to but some prices.
The re-engraving Dies go till 1960. After very few was re-engraved. the cost for this operation was to high comparative to reuse other Dies.
You put a photo of 1960 and COOP of 1953 which could be legitimate or qualify for re-engraved Dies, and even there is very disputable legitims.
I thing we imagine to much instead to focus of the reality.
Please read my previous post here to understand what is involve in an re-engraving. the Mint will not pay for this when the cost of a penny production is 1.79 cents
