Air test US Gold coin

[The Fog]

Does anyone own a US Gold Coin and a Safari? If so would it be possible to air test one and post what #'s it rings out at? I'm very curious what the tone and #'s are.

yeah, I'd like to know where they come in too. Maybe test a couple different gold denominations as well.

be even better if they put it in something safe and put it under a plug, but that probably asking too much.

I have the Safari and a $10 Indian gold. I use the all metal with the ferrous tones and I put the coin on the ground. There is some magnetite in the soil but I got a very high tone and a solid 36 readout. It is a 1908 by the way. Ok there you go.

Thanks a ton John! I tested a solid gold ring I found from 1780 and it rang in at 36 as well. I found this to be odd since that is outside the gold spectrum when you look at the safari interface. 36 borders the high end of copper and low end of silver. Makes me feel better not digging some of those iffy #'s between 14 and 28. Thanks again. Although I still wonder why solid gold doesn't ring in as gold on the control box.

Be carefull most cold rings are on 12-20 range

I hunt primarily in heavily wooded areas, cellar holes, etc. so I don't run into much jewelry. My main concern was gold coins. I do have some gold jewelry and it rings in 36 as well. I wonder if those rings between 12-20 are low Karat #'s?

Mostly white cold, its called white cold here. And old 1800s cold goes to this area to. Same thing with tiny hammered coins cold and silver to, they go to foil range.

Most gold rings would read lower than the gold coin I tested. I figure that the detector is showing the impurities with such a high reading of the $10 Indian.

The 1908 Indian is 90% solid gold according to coinfacts. I'll have to do some more air tests on some gold pendants I have at home.

That is a strange reading for a gold coin. It's right on up there with some pennys. I was figuring it would show up around 20 or so.

I hope all the US gold coins ring in that high, it's right in my wheelhouse for the custom coin mode I run. I don't swing beaches, parks, tot lots etc. so it's pretty rare to run into much jewelry, but ya just never know where someting is gonna show up... that's the beauty of the hobby. My buddy and I were hunting an old 1600-1700's farm field and he found the wheelbarrow monopoly game piece! That's a head scratcher.

The gold wedding band rang in at 36. The 1" x 1" 14 KT necklace pendant rang in at 16. So I'm guessing that the purer gold runs high.

 

[marxionu]

Purer gold runs lower.

 

[The Fog]

double posted.

 

[marxionu]

Yes i made mistake. Sry

 

[The Fog]

That doesn't make sense, The US gold Indian coin is 90% gold, that would make it 22 kt. and it rings in at 36. The ring I have from the late 1700's is almost pure and rings in at 36 as well. the 14kt pendant I airtested is only 58% gold and rings in at 20. the chart you posted from Andy's book shows a 9kt ring which is only 37% gold ringing in at 8. So purer gold must ring higher, unless I'm missing something.

I just air tested an 1886 S $5 Liberty head piece in AU condx. and it read at 32 on the Safari.

Thanks John. It's highly unlikely I'll run into many gold coins in the ground but it's nice to know where they may ring in at.
