I stumbled across this video on Youtube, I'm not sure if it's real, it seems unrealistic, far too much gold and huge bits.... The killer is the 90 gram.
The SS Central America had lots of coins and lots of treasure to say the least. We has a presentation (with coins and gold nuggets) at a PCSC meeting in Downey, California last year. The author said this book was coming.
I don't see much of a preview online but it may be a reference book that will show up in your local library!
Miners have unearthed an ultra-rare diamond with a second diamond inside it.
The inner gem is loose inside the first diamond, moving around freely — and could be the first example of such a diamond ever found in the world.
This rare gem is believed to have formed around 800 million years ago.
It was dug up by Russian diamond miners Alrosa at the Nyurba mine in Siberia.
Scientists then used X-rays and other scanning techniques to confirm the presence of a second diamond inside the first. A diamond within a diamond has wowed the world.Source:Supplied
“Based on the results of the study, the scientists made a hypothesis about how the crystal was formed,” Alrosa said.
“According to them, there was an internal diamond at first, and the external one was formed during the subsequent stages of growth.”
The gem has been dubbed the Matryoshka diamond after the Russian nesting dolls of the same name.
The outer stone weighs 0.62 carats, while the inner gem weighs 0.02 carats.
“As far as we know, there has been no such diamond in the history of global diamond mining,” said Oleg Kovalchuk, of Alrosa.
“This is really a unique creation of nature, especially since nature abhors a vacuum.

“Usually, in a case like this, the minerals would be replaced by others without forming a cavity.”
He added: “The most interesting thing for us was to find out how the air space between the inner and outer diamonds was formed,” said Oleg Kovalchuk, of Alrosa.
The diamond will now be sent to the Gemological Institute of America for further analysis. Researchers haven’t estimated its worth yet — it will be difficult due to the gem’s rarity, they say.
However, they do have one theory as to how it formed.
“A layer of porous polycrystalline diamond substance was formed inside the diamond because of ultra-fast growth,” Alrosa scientists explain.
“And more aggressive mantle processes subsequently dissolved it.
“Due to the presence of the dissolved layer, one diamond began to move freely inside another — just like a Matryoshka nesting doll.”
Australian Coin Hunters in the future are in for some quite amusing finds, see the new range of $1 coins about to hit the streets
See the story and full collection here, a new Aussie themed coin for every letter of the alphabet.
Pretty cool idea, I'd like one of each
A whole new and more valuable collectable craze is about to sweep across Australia with the announcement of the Great Aussie Coin Hunt.
Australia Post and the Royal Australian Mint will release millions of $1 coins from today featuring classic Australian themes such as the Hills hoist, a quokka and an Esky.
There will be a different design for each letter of the alphabet with the first six available now.
A will feature Australia Post, F for footy, I for Iced VoVo, M for meat pie, S for surf life saving and X for the tiny township of Xantippe.

New coins will then be released every Monday until October 21, culminating in Z for the summer staple Zooper Dooper.
But there’s a catch.
The only way to get your hands on the iconic coins will be to make a purchase at an Australia Post store and receive the limited edition $1 coins in the change.

“We want everyone to get involved,” Australia Post consumer and community executive general manager Nicole Sheffield said.
“Not only will it be really exciting to hunt for all the coins and build an amazing collection, but each and every coin opens up the opportunity for wonderful conversations about quintessential Australian life.
“It’s a great way for grandparents to connect with grandchildren, and for all of us to share our own experiences and memories with each other — both here and with friends and family overseas.”

The massive campaign is the biggest minting and release of $1 coins since they were created in 1984.
“We are excited that The Great Aussie Coin Hunt has now officially launched, giving families and all Australians the opportunity to participate in a fun and educational nationwide coin hunt,” assistant treasurer Michael Sukkar said.
