 $1 and $2 coin ID numbers(Read 818 times)
$1 and $2 coin ID numbers on: August 28, 2017, 16:21
Is it normal for there to be a range in target ID's of very new and shiny "goldies" when compared to the older and dull ones?
An example is an old and dull 1985 $1 coin which reads as 67. A newer and much shinier 2016 $1 coin reads 70 and sometimes 72.
I have learnt that the composition has remained unchanged over the years.
Thanks,
Tony

Hi Tony.
On my Whites v3i  the $2 coins vdi  54, 55,  $1 56, 57, 58, 59, 60. It could be they are a bit wonky with their composition. And their is some fake $2 coins around .  You just have to  dig the varied vdis up other wise  you will be leaving them for someone else. I use mixed mode and program the discrimination in to except all vdi dropping 95 so accepting -95 through to +94 And then accept all the 5, 10, 20. 50. $1 & $2
By giving each a tone only on the vdi of each coin so if you hit a 5 cent coin you will get distinct tone and all other targets are blocked out only the tone of our 6 coins will be heard With 1 & 2 cents blocked out.
Regards Beeepppnnn.

Thanks Ray,
So basically, the shinier and smoother the coin the higher it will read (coin for coin)......encourages stronger eddy currents.

Just swept over a 100 different $1 and $2 coins.
Every $2 coin (all dates) read either 60 or 62
Every $1 coin (except the 1985) read either 70 or 72. The older $1 coin read 67.
Pretty happy with that actually....this is for the White's MX5.

I dig everything between 67 and 74 with the MX 5 and MXT , have had some some funny numbers come up trumps like the time i found no less than 6 $1 coins sitting on top of each other ! Readout was in the 80's but was too good a signal to ignore .

A few other things tony that have a sway on the vdi of a target the age of the coin attacked by the soil, angle of the coin lying in the ground , near other targets, and the depth of the coin. There is some many things that do pop up in this metal detecting hobby.

Regards Beeepppnnn.

Don't the $2 read as 62 on your MX5....this is with the stock concentric coil.....hope you are not leaving the $2 coins for Ray.... ;D

Sounds like Ray is fairly deadly !  I am using the Eclipse 6x10 coil on the MXT and a Mars sniper on the MX 5 . Those numbers seem to work for me , i hope i am not leaving any too ! I notice your machine is reading $1 coins at 70-72 , my MXT reads 72-74 on those with 75 always being junk . I have not done much goldie hunting with the MX 5 yet and what i have done has been on the beach in wet sand  , now you have me worried , will probably do some testing tomorrow . I don't have the standard concentric for the MX 5 .

You should be fine...I see you are using a DD coil on the MX5 which give different numbers to a concentric...

Gday Tony , did some testing today and all i can say is , wow different coils make a difference ! I hadn't really thought about that much so when i tested the MX 5 with the Mars Sniper coil fitted today the learning curve went up . You get 70/72 for a $1 coin with your setup , i get a rock solid 74 out to 6 inches no matter what attitude the coin is in . I won't dig coins any deeper than 6 inches in public grassed areas and then only when the ground is really wet . The big difference was the $2 coin , you read 60/62 . My setup gives 67 at 5 to 6 inches deep and shallower than 4 inches locks in at 70/72 !  Fully 10 points difference with another coil . And these numbers get shaky when the coin gets on edge , surface area ? I suppose this is old hat to the blokes that have been doing this for years but to me as a bit of a beep and dig bloke it was an eye opener , especially as the MX 5 is reputed to be built on the MXT platform with a rumored extra bit of power being sent to the coil . A lesson for me out of this is assume nothing and test every coil for purpose . By the way , nice work getting a $100 up already , a good day here is about 10/12 bucks but usually 4 or 5 $  so plenty of my hunts to equal a few of yours . Good hunting .

My thoughts,I think it all depends on is the coin laying flat or on an slope in the ground,different angles different I'd numbers.
