Some of mine show this problem. Some worse than others. I had been meaning to post about it
These are the so-called "error coins" from the first batch, where there is no relief in the metal coin for the key paper to rest in, which makes the hologram sticker bulge a bit. The deterioration appears to be worst at the edges of the bulge.

Well I guess that explains it then. Thanks for clarifying. Its interesting how much of a difference a little recession on the coin makes Cheesy

The Encyclopedia of Physical Bitcoins and Crypto-Currencies- Revised Edition by Elias Ahonen, p.201, mentions this 'structural stress' has been documented to cause some damage to the hologram even for coins properly stored, ex- above the 'L' and below the first-bits.

Interesting....
Possibility that the holograms were made by the same manufacturer for both the Lealanas and Ravenbits around the same time???

It could be; however, in this case it seems the root cause is more in line with the absence of the private key chamfer/pit as opposed to hologram manufacturing, IMHO for what it's worth.
