Himyarite coin with ancient South Arabian script

Unicode has included letters for the ancient South Arabian script used in Himyarite coins for a long time but I have never seen them used except in sites about Unicode itself. Here is a coin from mint ???????????????? (=RYDN, Raidan/Raydan, at Zafar in Yemen). Show More Summary

XRF testing

At the ANS seminar Counterfeits: the Threat to Collecting and Scholarship several people from the museum community remarked analyzing the metal in coins using X-ray fluorescence (XRF).

The American Numismatic Society hosted a seminar on Counterfeits: the Threat to Collecting and Scholarship with presentations by David Hendin, Robert Hoge, and Ute Wartenberg. For me the most exciting part was inspecting dies from the...Show More Summary

Liar, Liar, Pants on Fire...

The Committee for Cultural Policy has pointed out on several past occasions that exaggerated media reports, of Islamic State (ISIS) income from the sale of looted antiquities to art and coin collecting communities, are and have from the start been unfounded. Show More Summary

The difficulty of photographing gold coins

Weekly Numismatic World News for August 27, 2017

This week, the BBC reported about Toby Robyns, a 52-year-old ambulance driver from the U.K., who may be facing an up to three-year prison sentence for trying to take home ancient coins he found on a beach in Turkey. Immediately, my thoughts turned to a story I wrote about my friends in a similar situation. […]

How about a Numismatic World News Podcast?

For the last few weeks, I have been publishing the Weekly Numismatic World News every Sunday evenings. These posts consist of links to the articles that I find around the Interwebs along with a commentary on one of the articles or something else related to the news. I had an idea. Rather than just post […]

Numismatic Eclipse

As we wait for the shadow of the moon to trek across the United States from Oregon to South Carolina, I was curious as to whether there were coins ever created to commemorate any of the past eclipses regardless of location. Allowing an online search engine to help, I was able to find a few […]

Weekly Numismatic World News for August 20, 2017

In my nearly 12 years of writing this blog and occasionally delving into the reasons for the fluctuating prices of precious metals and their impact on the numismatic market, there have been some fundamentals that have driven that market. As I was reminded in one of the articles in today’s list, “Is Now The Time […]

Unlucky at the ATM

You need a quick amount of cash. After all, not every transaction can be made with a credit card. You hop in the car and drive to the bank to use the ATM. Within seconds, the machine spits out money and you drive away. Early the next morning you look at the bills and notice […]

Learning from History using Numismatics

One of the most popular aphorisms was written by philosopher and essayist George Santayana: “Those who cannot remember the past are condemned to repeat it.” Although it was one line in Volume 1 of his five volume The Life of Reason, the statement is so profound that it stands out as a seminal statement. Events […]

Adding Collecting Guides

Over the last few weeks, I have been working on a few writing projects that include primers about collecting numismatics. While some of these articles have allowed me to repurpose blog posts, I have had to create some content not posted before. In the past, I posted a few including the series on small dollars […]

Weekly Numismatic World News for August 13, 2017

The reasons why counterfeiters are successful is that people do not pay attention. Even when people do allegedly pay attention, it is almost as if the brain is not engaging. A report from the U.K. says that people returning from mainland Europe are trying to pass euros because they look like the new £1 coin. […]

Lack of leadership at the U.S. Mint

Following the sell out of the 225th Anniversary Enhanced Uncirculated Coin Set, a few readers asked if I was going to post a comment. I declined to let the rest of the industry have this discussion. I would rather have a discussion about a different issue related to the U.S. Mint: the lack of leadership. […]

Sirius Collecting

Ancient Romans used to measure time by the position of the stars. One of the stars they observed was Sirius because it was the brightest star in the sky. During their observations, they found that starting about 20 days prior to its apex and 20 days that follow, the temperatures would be its hottest. This […]

A sign of the times?

Over the past decade, collectors of ancient coins have been faced with constant pressure from left wing radicals of academia—particularly the archaeological community leadership and their sycophants. Among the ardent supporters of anti-collector groups are a small but well entrenched cadre of bureaucrats in Washington. Show More Summary

Unintended Consequences

Three years ago, coin collector and hobby advocate Scott Barman posted on his blog an insightful article about the nature of what others have described as ideologically inspired bureaucratic overreach. He named the post "An Ancient Dilemma" and discussed the issue of unintended consequences in an era of "hyper-partisanship". Show More Summary

Xingyu Pan and imageLaure Tougne have published a paper describing their database of digits extracted from scans of modern coins. The database of 3000+ images itself cannot be directly downloaded. They explain here that you may request it from them. Show More Summary

Antiquities Memorandum of Understanding with Libya

Please read Cultural Property Observer and comment on the Libyan MOU. If the MOU is completed and includes coins it will become difficult for Americans to buy ancient coins from Kyrene in European auctions. It will also be difficult to import Ottoman coins from the territory of modern Libya. Do it this weekend or it will be too late.

Recognizing Roman coins with neural networks

Jongpil Kim of Rutgers university reports a neural network capable of correctly recognizing the emperor 73% of the time from coin images. The reverse type is recognized 67% of the time. The report is available on SEQAM and the paper is available by clicking PDF on this Cornell library site.
