Incredible 1963 Multi-Error Duo: Mexico Retained Cud/Lamination & Ceylon Severe Obverse Rim Fin (Edg

Hey everyone, I wanted to share a couple of highly dramatic, vintage 1963 international striking errors that I've been studying in my collection. Both of these exhibit incredible, textbook diagnostics of progressive minting failures, and I'd love to hear your thoughts on them!
SPECIMEN 1: 1963 Mexico Cinco Centavos (Retained Rim Cud & Lamination)
This piece is a fantastic study in multi-stage progressive die failure.

• The Cud: It features a highly prominent, raised retained rim cud located on the right obverse border. The metal has completely bled inward, swallowing and heavily distorting the bottom loop of the "3" in the 1963 date.
• Diagnostics: Looking at the edge, you can see the classic uneven thickness where the fractured, loose die chunk sank backward under the pressure of the strike. Furthermore, the field and Josefa’s portrait show intense mechanical stress streaking from the failing die face, accompanied by a distinct planchet lamination flaw.

SPECIMEN 2: 1963 Ceylon (Sri Lanka) 1 Rupee (Severe Tilted Die Obverse Rim Fin)
This crown-sized copper-nickel coin features some of the most dramatic, crisp rim finning I have ever encountered on a foreign issue.

• The Obverse Fin: The hammer die came down with immense, uneven vertical pressure, extruding a razor-sharp "wire lip" or flange around roughly 80% of the coin's perimeter. When looking straight down at the obverse face, it creates the fascinating visual illusion of a "three-layer rim."
• The Reverse & Edge: Interestingly, this error is strictly isolated to the obverse face—the reverse rim profile remains entirely flat and normal. I took a close look at the specialized inner indented security edge running along the center groove, and the security reeding remains completely straight and un-smeared. This confirms that the retaining collar stayed perfectly rigid, while a severe die tilt forced the metal to shoot vertically up the neck of the obverse die.

I’ve attached clear macro close-ups of the date-covering cud, the edge thickness variations, and the sharp obverse wire flange below.
Have any of you encountered such high-coverage rim finning on these specific Ceylon security-edge issues before? I’d love to hear your opinions on the overall eye appeal of this 1963 pair!

Hello and welcome to CoinTalk,

I'm one of the resident mint error specialists here on this forum.
41 years experience in collecting, studying and attributing true mint errors.

The first coin seems to have a Planchet issue.
But it also has a lot of post mint damage. Looks bad.

The second coin is nothing really spectacular IMHO.

I wouldn't consider them "Highly Dramatic" errors

Eye appeal? Incredible? None

But thanks for sharing.

 

Welcome to CoinTalk! Thanks for sharing those with us. I really like the design of the Rupee. As for paddyman98, he is the guy to go to for errors. You can trust his opinion.
