v3i and VDI of 19 for Ben Franklin 50 cent

[wagon wheel]

Interesting experience yesterday while mding...I hit a strong 19 vdi with my V3i in some extremely dry soil here in Eastern Utah...dug the plug and at about 6 inches out comes a 1952 Franklin 50 cent piece instead of the anticipated nickle. :crazy:

That IS unusual. Did you recheck the hole? I've had pocket spills that pull down the VDI of larger, silver coins. Don't ask me why. :-\

yep...checked it two or three times. :crazy:

I would think the first guess I would have is that the half was probably standing straight up. This would probably give it a much lower reading. Add some rust in the area and maybe a target close by and some mineralisation and maybe that could drag the numbers down. But 19 is really low. It is't counterfeit, is it?? Did it read low after it was pulled from the ground too??

It might help to understand what is going on if we could see your program settings.

I ran an air test on the coin today and with the Salt Beach and salt comp program I was running yesterday it VDI'ed at between 85 and 92. I did stand the coin on edge and it was for sure a much lower VDI...you may have solved the question. :thinkingabout:
