isn't such a bad combination.
Your posted settings, 'testing' and 'results-to-date', however, make me wonder.
Sensitivity = 80: Was there a reason you selected '80'? Was there EMI if you adjusted higher? Was there any unstable conditions with EMI when set at '80'?
Disc. = 20: Good enough to knock out quite a few nails, maybe 1-3 higher numbers to get more iron nails rejected, but did you use a setting of '20' because that was needed to knock out trash that was already present? Are you bothered by iron trash, or does it matter if you hear some of it? Personally, I prefer to work all of the Teknetics models so that I hear all of the targets they might allow, including iron, but i also like an audio response to better define likely iron trash.
Tone ID = 3: That's a good Tone selection, and I like it much better than '3b'. However, my personal preference is to hunt in the default setting of '1', but based upon the site and what I am after I might opt for 1+ or 2+. I very seldom use anything but these three Tone ID options on the T2, favoring 2+ if I am listening to everything (I prefer a '0' Disc. level most of the time), or 1 or 1+ Tones if there isn't a lot of iron and I just want to hear every target present.
GB = 57: Lucky you to have such mellow ground, compared with most sites I hunt. So far this week I haven't hit any dirt, gravel or grassy area that would GB below 75-76, and most was up in the mid 80's to almost 90 range.

... now I know that for this to work like it should they should stay in the ground for a while but I could not get a sound on either coin is that normal?
Yes, it is extremely 'normal' to not get a nice and proper VDI or Target ID from a freshly-buried test target.
You also might not get/can't get a 'proper' VDI/TID from a coin that is placed under a dense mineral body, quite often, such as a big dirt clod or a flattish rock of, let's say, 6"X9"x2" thick. That's the measurement of my 'Homestead Rock' that I picked up from a Central Oregon homestead back in the early '90s. That flattish style rock was used for the chimney and wall until they decayed and fell all about the site.
I've used other rocks to demonstrate quirky behavior, or grabbed a dirt clod in a plowed field to show folks how that, too, can hamper any target detection, or only signal as Iron on the TID/VDI or audio Tone ID ...
IF the detector can be adjusted to a true, all metal accept minimum Discriminate setting.
When you have challenging ground conditions, such as very mineralized ground, rocks, dense mineral bodies,
or freshly disturbed dirt, that can restrict target detection.
If your Discriminate level is too high, in such a condition, you might not signal on such a fresh-buried sample.
Also, as stated below, if you have a nearby rejected piece of junk, such as iron when your Disc. was set at '20', then that could also impair target detection.

On my air test same settings I can get 12in on the quarter and 10 to 11 on the dime.
That was an in-air sampling. There wasn't any ground signal to deal with so what you might see is a best-case scenario of what the results would be if you hunted in a layer of foam peanuts, or .... air.

Pleased you should be because the T2 has a lot of potential. I don't know what make or model detectors you have used in the past, but the T2 is a serious contender for one of the better choices ever, at least for many applications.
It does take time to learn and master the T2, just like any detector, and the best was to accomplish that is NOT by teasing it with any silly 'air test' that YOU can do, but by finding out what the T2 can do in a natural hunting environment.

I have found a wheat at 8 in so far just a little confused on the test bed any insight?
So, in real-life hunting you found a wheat cent at about 8"? that's great and it shows some of what the T2 is capable of. What settings did you use to make that find? Were you using the stock 11" DD coil? Was it a clean site iof similar soil make-up, or something different?
Just get out and hunt with the T2. Learn it. Let it tell you what is there via the Audio response and use of a Tone ID selection (I prefer 2+, 1 or 1+ in that order). Learn to interpret the VDI response (which I prefer) and the Target ID (I am less a fan of TID readings than the VDI).
You can leave the 'Sample Coins' if they are safe and then return to that site and check them about this time next year. In the mean time, just go detecting and learn the abilities of the Tek. T2.
What left me wondering? Why you decided to plant a test area, knowing that the targets should stay there for a while to begin with. I wonder why a test area when you already found a wheatie at 8", and you know the best-case potential from the 'air test.'
I also wonder if you GB'ed and then used the All Metal mode to make sure everything was cleaned out of the area where you planted the sample coins? Also, if you didn't get the buried targets in the Disc. mode, did you check the response in the All Metal mode? That also might have alerted you of any nearby masking trash.

is that normal ? On my air test same settings I can get 12in on the quarter and 10 to 11 on the dime. Now I have only owned this machine for a week and a half and am very pleased with it I have found a wheat at 8 in so far just a little confused on the test bed any insight ?
