1937 Crown error?

I picked up this 1937 Crown a while ago and forgot about it. It has what looks to be some sort of delamination or some sort of strike problem, particularly at 1:00 and to a lesser extent at 6:00.

Or has it just been mistreated at some point?

Thoughts from the SS elders?

Thanks

EDIT: forgot to mention, the reverse is perfect.

I aint no expert, but it looks like some sort of erosion...like something has eaten it away

 

Interesting coin - not sure what would have caused it.

In case you are sitting on a monster, id suggest for you to become a member and upload the foto on site below

they have numismatic masters there.

 

IMHO it looks a lot like electrolytic corrosion, dissimilar metals (Copper or Nickel coins) laying in contact in the presence of moisture. The surface will erode & leave somewhat originally defined detail behind as it has in this picture. A bunch of old shipwreck style 1966 50 cents I purchased had a similar effect. They were sitting for years in a rusted milk tin half full of water. That turned the whole mixture into a battery. They accidentally fell into a melting pot some time later.

 

Thanks Gents for the responses. I might take up Thucy's suggestion and post a pic on that site. Interesting thought Dyno, maybe!
