Lincoln Cent Struck On A 2. 8 Gram Screw, PCGS MS-64+

Notice the bolt head is not damaged and that the other end of the bolt is intact as well. Also that the bolt is bent upward toward the obv side. The bolt was not IN the coining chamber it was laying on top of the collar and spanning the chamber. The obv was the hammer die and hit the bolt bending it down into the collar. So the obv side took the full impact but most of the force was dissipated in bending the bolt and it didn't make strong contact with the rev die. So on the rev the threads were flattened but only part of the design was transferred to the bolt.

Coop, just a slight addition to the screw bolt issue. Typically a Bolt needs a nut, where a screw does not. The exception to that rule are Machine screws, they have flat bottom like bolts but do not need a nut. Yet they are called machine Screws.

Dan

A plus grade no less!

Uh huh.



Makes a good deal of free advertising for PCGS.

As the grader mentioned, comparison with others is what they depend on to base their grade opinions.

Hence a reality check would have been better on the label such as "Appears like an MS64+ Lincoln."

Still cannot get over the plus

Hey...great idea coop!

You could make millions opening up a PBGS company!

I think though I would included metal hardness into the grading standards as it might make it a bit more marketable and comprehensive. "First threaded" labels...Gear picture labels...man the potential is almost limitless.


Actually there is a date nail hobby (RR related) where no professional grading system exists...unfortunately the hobby is almost dead..rats...missed my chance!

I wonder, if the treads were stripped would it have received a "details" grade?

This is something else to take into consideration to start up the PBGS service.

I think taking bolt head scarring from previous screwdriver use in the slot on top would also be a very important area to asses for damage/grading. The tip might needs its own assessment as well.

We need to get together a group of people who have been handling/selling bolts for years to start this up. Every bolt a contractor uses (no matter their own personal experience with handling hundreds and thousands of bolts) should be submitted to PBGS in order to get a professional opinion on the bolt as to its trustworthiness.

Hmmm...its the first time a business effort like ths has been tried for bolts, so maybe ABACS: American Bolt Association Certification Services

OK...OK... I'll stop.

Its just amusing to me mimicking "reality" can sometimes be ridiculous

Thus the split plating on the strong strikes that expose the zinc.

Whoa there. I just looked at the pic again. The bolt itself is definitely damaged by the die impact. It will never fit a corresponding nut again. And there are most definitely rim dings on the head as well as what is almost certainly rust/corrosion in the groove.

How is this not a details grade and/or labeled as damaged/corroded/environmental damage etc.?

They need to crack it out and re-submit. It should be covered by the PCGS guarantee which says if you think a submission is over graded, you can send it in and they will not charge you if they lessen the grade.
