Just a side note. If the illustrated coin is evaluated and determined to be "Not Authentic," it is possible it can be returned for a full refund. Title (ownership) cannot pass on a counterfeit.

You'll get more help if you tell members which coin albums you are considering.

Idle time damage, or someone attempting to make "errors" to sell on some goofy web site.

Vinegar contains acetic acid. Coins of zinc and copper do not like acetic acid. Next time, use the vinegar for dipping your dinner salad and not your coins.

On a Fictitious Note: A "later die state" is one West of the Mississippi River; these are California and Nevada, and almost Oregon. "Early die states" are East of the Mississippi; these are Pennsylvania, Louisiana, North Carolina and Georgia, and almost New York.

Consider consigning the 1776 piece to Heritage or another reputable auction company.They can tell you if it is marketable and have it authenticated. In today's coin market your pewter piece is almost unsaleable without independent authentication.

At least it's not a new thing.....

First, use a copy of the Guide Book of US Coins and categorize all the coins. Pay special attention to those in plastic holders from PCGS and NGC - the "grades" are likely to be reasonably accurate. Second, list the graded coins and check their approximate values in the Guide Book. This will give you a rough idea of retail value. Third, do the same for non-slabbed coins by comparing them to those already graded and, following the comments at the heading for each coin design, estimate the grade and value of each piece. Fourth, many common coins, such as worn nickels and Lincoln cents, will likely be worth almost face value. Fifth, silver and gold coins will be worth their bullion content at a minimum. Once you've cataloged and estimated value, you can post coins here and ask members for input. This will help refine the scope and value of your coins. If the 1776 continental piece is an example, you might have many valuable pieces in the collection.

No....not pareidolia, That the is original hidden Sanskrit inscription, accidentally transferred to Lincoln's hair by a Hare Krishna devotee working at the Philadelphia Mint in 1940. The circled inscription, loosely translated, reads: "Hey Babe. Meet me down by the levy at 7."

Common in bust-design halves. They were often crowded together in small barrels and bags, and -- well -- some of the Miss Liberties got pregnant. The stretch marks are what happens not too long before the halves give birth to half-dimes. Eventually, half-dimes grow up to be quarters and sometimes halves - but rarely dollars.

How about describing the coin, and posting a photo (sharp, clear, good color). Of course, from the initial description you might have a Russian Constantine ruble worth $2+ million, or a parking lot cent worth 1-cent if anyone will accept it.

A proof coin is usually struck at above normal pressure, or, for modern proofs after 1969, struck twice in a special press. Post 1968 proofs should have better detail than circulation coins, meaning a greater proportion of "full step" Jefferson nickels.

Here's OPs coin cropped and color balanced from the invoice photo.

Agreed. Or possibly damage.

No. It's a fuzzy-photo "P."

I'm sure you will see it. They'll update the original material and that's about it. Interestingly he has no research credential in US coinage. (PS: Do not throw your shoes at the TV....!)

No TPG encapsulates coins in a closed, moisture-free, neutral atmosphere such as nitrogen, helium, or argon. No slab is routinely hermetically sealed. There is very limited information on whether archival labels and ink are used, or if any internal slab parts (prongs, gaskets, etc.) are completely inert. Even the plastic used in the slabs can be suspect.

Bills were rendered monthly. Was this just July, as stated on the bill header? Seems like a huge volume of supplies, though. The alternative could be quarterly use, or simply the supplies received in July but actually intended for various time periods. We don't have the account journals to allow checking.

Can't determine anything from the tiny photos. 1922 HR pieces were not restruck with standard 1922 dies, or any other dies.

You could send them your suggestion (from above) along with the idea of bringing some DE books to shows.

Dies are made individually, then some are polished for making proof coins. Polished dies are examined more closely than those used for circulation. Hence, the proportion of doubled dies used for proof coins is likely much less than for circulation coins.

We exchange information occasionally. They have only a few books they've published, so it is not something on their to-do list. The company is much larger than just the coin business.

Correct. These were the "house" shutters around the refining pots. Refining was one of the most dangerous jobs at the mint - fumes, heavy ceramic pots filled with hot acid, multiple operations going on simultaneously, limited protective clothing (leather aprons), no optimized chemical processes, pauses for intermediate assays, etc.

A better photo will help....but it does not look like anything except a date in the teens. (Remember the HS Prom -- and those teen dates? Always had to buy a corsage for the girl.)
