New page (technical problem sold): Al Marco Adjustment
« on: January 31, 2024, 09:16:46 pm »
As discussed in another thread (https://www.forumancientcoins.com/board/index.php?topic=128278.msg793454#msg793454), I've added a Numiswiki entry for "Al Marco Adjustment."
I was getting an error message so I revised the title (trying "Al Marco Adjustment" instead of "Al Marco Weight Adjustment"), and it worked.

There's also an entry for "Stannard Adjustment" -- I've cross-referenced them. (May be better to combine?)

Quote
Al Marco Adjustment

Weight adjustment marks, sometimes called “Stannard gouges” or "Stannard adjustment" marks, are frequently found on Roman Republican denarii, and occasionally on certain Greek or Roman Imperial coins. They were made by scooping out small amounts of metal before the blank was struck, to reduce weight. Specifically, the goal was to reduce the total weight of a batch of denarii, known as “al marco” weight adjustment, rather than to reduce the weight of any single coin, known as “al peso” weight adjustment.

The practice indicates that mint workers prioritized a certain number of coins for a specified total weight (or, put differently, an average weight per coin in a batch), rather than achieving a precise weight for each individual specimen.

This explanation for the phenomenon was published by Clive Stannard in his 1993 essay, "The Adjustment al marco of the Weight of Roman Republican Denarii Blanks by Gouging,” in Metallurgy vol. 3 (Archibald & Cowell, eds.; London: RNS). Examining museum specimens, Stannard found that 2.53% of Roman Republican denarii showed evidence of al marco adjustment gouges.

When it comes to NumisWiki page names, they should be based on what is more likely to generate auto links. So, if some people will write Stannard adjustment and others will write al marco adjustment, then two pages are better than one.

Nice job Curtis!

I've always said Ad Marco  Is it Al Marco?

Seems the pdf link doesn't work for me
