Real Pt or not?

[cluelessguy]

hi guys.. am just new here. anyway i hope you can more or less assess if this is a real platinum bar or not. According to my bro the size of this thing is like a hersheys chocolate bar and weighs about 3 kilos.. your inputs will be greatly appreciated. Thanks!

clueless,

Welcome to Treasure Net !!

I've heard that testing for platinum can be done by putting the object in hydrogen peroxide. Platinum acts as a catalyst which reacts with the hydrogen peroxide releasing oxygen. If it bubbles, it MAY BE platinum.
However, the test in hydrogen peroxide is not a conclusive test as it also reacts with items; silver, for one.

If it was mine .I would heat it with a cutting torch. Plat. melts at 3214.9 degrees. You can't get a torch that hot. Plat will get White hot ,but won't melt. If it melts it's not Plat.

This is very interesting at first I saw USSR and then the hammer and sickle, let us know what it is.

 

[5woodluther]

If the density of Pt is 21.45 g/cc, and we take the size of a hershey bar to be 7 cm X 16 cm x 1cm thick, we would have a volume of 112cc. So 112cc X 21.45 g/cc would be 2,397 grams of platinum.

I guess that is pretty close to your 3 Kilos. If it is only 900 platinum, it would probably have a density nearer to gold in the 19 - 19.5 range.


Just some data

 

[CRUSADER]

My assessment from the picture with no USSR Bar knowledge is that it is very poorly cast & I would expect cleaner letters & symbols on a bar so important. Otherwise, who ever made it would be laughed at for poor smithing.

 

[CSA2K]

3 kilos is roughly 96 troy ounces. Platinum is currently trading at US 1693 per.. thats a whole lota Hershey bars..

I'd find an expert real quick!

 

[Mackaydon]

The handle of the sickle is on the wrong side; another 'red flag'; and the hammer isn't shaped correctly.

 

[EagleDown]

Yep! I'll have to ride with CRUSADER on this one.

I hope your fantasy find works out for you but I'm skeptical. The Soviet Union didn't use USSR, that's our translation. Theirs looks more like CCCP. And that's the ugliest hammer and sickle I've ever seen. And if someone actually lost a 3-kilo bar of platinum you'd have met them on your hunt, still looking for it. I think souvenir but I wish you otherwise. Good luck.

[mikusek]

Wouldn't the USSR have stamped or molded CCCP on something like this

I'm a clueless guy too! Sure hope it's real for ya!!!!!!!!!!!! God Bless Chris
