Anatomy of a Die Clash, Part 2: Two-Leaf LFEs

RKKay

For those of you who are interested, I have now added pages discussing both the die clashes from 1855 Four-Leaf LFEs and those from the 1854 (and 1855) Two-Leaf LFEs. Here is a link to the original forum post on the Four-Leaf LFEs. Here is a link to it on my website.

Here's the link to the discussion on Two-Leaf LFE die clashes.

Thanks, Jesse. Question for you on the 1855 Four-Leaf you posted. Has it had metallurgical testing? I see it weighs 5.93 grams (91.51 grains). Of the LFEs I've tested, ten have come back as 100% copper (or nearly 100%). The least any of those ten LFEs weighed was 98.46 grains. Of the approximately seventy that have come back as bronze, every one has fallen in the range of 88.7 to 97.7 grains. Thanks. Rick

Very good work, and a real concise and understandable dissertation.

Well done!

@RKKay , As far as I know it has not received any metallurgical testing. However, I see (based on your results) that there's only 14% chance that it's copper and not bronze. As such, I just updated our internal files from Copper to Bronze, as well as for our other example that weighs 5.88g (albeit, slightly worn). These changes will take a little bit of time before these changes are reflected on the website (after the next mass update). Thanks for this info!

Thanks for the info on your pieces. If you need any info from me, let me know.
