I can see where you might pull a 45 on some of the top row (rusty caps)even then in all metal it should give a ferrous grunt at the start or end of the tone. But for the bottom row ... well I just don't get that at all.
That nickel should be hitting a solid 12 or very close, the quarter at 43, zinc 30-33 at the most and the beaver tail should sound and hit like the nickel.
Maybe that funky black sand has done a number on them ?
Have you checked your coil cover to make sure it's not full of the black sand ?
Other than that, I'm out of ideas, maybe you need to send it in to have the software reloaded because that's just not normal, especially on the low conductors ... IMO.
How's the depth and overall stability and does it seem to GB normal or is it real touchy even on good dirt ?

Have you tried resetting the detector to factory preset - both the patterns and the software?
1) Hold the PATTERNS touchpad when you turn it on and wait for the PE to appear
2) Turn it back off
3) Press and hold the MENU SELECT touchpad and turn it back on. Wait for the FP to appear.
If you still get a 45 no a zinc 1c and a nickel, your X-50 needs to take a short vacation in Las Vegas for some R&R and a good checkup . . . .

My brother had a 45 ID with nice sound, and dug a zinc penny 10 inches deep on the sands of Lake Michigan. Then we buried a quarter approx. 8 to 9 inches in the sand, and his X50 read 45 sweeping all around it. My mxt read it at the quarter number. Another friend of mine has experienced the same thing at a similar site, (inland fresh-water lake on the sandy shore). Dug a zinc at approx. 9 inches reading 45 on meter. Then he moved up in the grassy area and dug a few deep 45,s and got pull tabs.
Here's two different people that are confused and frustrated at deciding to dig a 45 signal or not to dig. 45 seems to come up alot on there machines. I have printed Andys' suggestion and will give it to my brother and see if this makes a difference. If not, then it appears that the unit needs to be sent in evidently.

<b>Maybe that funky black sand has done a number on them ?</b>
I think that and the moisture in the sand may be part of it. This is not heavy black sand like the previous site I hunted near the water, but there is some black sand mixed in. A lot of river silt mixed in here too.
<b>Have you checked your coil cover to make sure it's not full of the black sand ?</b>
I am not using a cover.
<b>How's the depth and overall stability and does it seem to GB normal or is it real touchy even on good dirt ?</b>
Stability is great and it GBs just fine (3 at this site), sens at 18-20 and using all metal 95% of the time. I haven't been inland with the XT50 for a while, but I don't recall any 45s that were coins. On the beach it will read coins correctly on the surface or if shallow, but if they're over 4" or so I sometimes get 45s. BTW, I thought I had a nickel (in the photo) as I've found dozens of nickels that looked just like it, but it turned out to be a wheat cent.
I buried each of the targets in the photo at 5" and all read 45 - none reads 45 on the surface of the sand.
An empty hole reads -9 in all metal, but each of the targets reads 45 in the bottom of the open hole.

each beach is going to be different. What I am going to offer is not guaranteed to resolve the issue, but to provide possible clues toward some solutions.
1. GB on a perfectly smooth, target free area. Put machine in AM and bobb coil from 1 inch to 10 inches high, like you were GB'ing, and note if detector reacts with a (-)9 or +45. If yes, reduce sensitivity until you get no response in AM. You may end up quite surprised about how low you need to go, possibly down around +10.
2. Now dig an empty hole about 8 inches deep, 6 inches round, and bobb coil in AM, and once again note at what sensitivity you get no response at.
3. Now this part is more experimental, scrape away about 6 inches of surface sand in a 2ft circle till you get down to the damp sand in a target free area. Now GB once again, and note the GB setting as it compares to the surface GB number, and then bobb the coil in AM to find a sensitivity level where it doesn't respond.
4. Also, are you noting when you dig targets that there are layers of black sand? So that the black sand is stacked like a cake as you go down through? Which will raise heck with the GB setting.
My overall guess is that you may be running the sensitivity too high. And the combination of salt & black sand may need a dual freq to prevent the target ID shift. Or there's enough black sand to chew up signal to prevent detection beyond 5 to 6 inches. Kind of like detecting inland at 9 to 10 inches, where you are at the limits of what the circuitry can reliably ID, so it throws up a 45, which I guess kinda says, there's something down there but I don't know what it is.
Please get back to us(the forum), because this is something interesting that doesn't get discussed much here. Too many dang relic hunters on here I reckon.

and maybe some environmental issues as well that's causing the 50 to ID differently ?
When I lived in Pensacola (usually neutral ground) there was a handful of sites that everything I used, whether it was a Explorer, CZ, MXT, DFX,etc. would read a full scale out from normal ... but the goods were still found.
I just had to remember to put myself in the right frame of mind when I hit those sites or become very frustrated. It was always fun to take other hunters there for their first time and watch their reactions for a little while before I told them what was going on

It sounds like a target phase shift. It happens here on the salt water beachs. The high mineralization cause's the targets to move high and lower in some case's than they would nomally respond. This is even the case with the Explorer. It is always a good idea to know the beach's you hunt on a regular bais(sp?).

Yes, -9 to 16 sens. 15 sens. no response, but needed to go to 13 sens if lowered to almost touching sand.
<b>2. Now dig an empty hole about 8 inches deep, 6 inches round, and bobb coil in AM, and once again note at what sensitivity you get no response at.</b>
Same as above, but we received some rain last night and the sand was damper than usual. I tested in the afternoon after the sun and wind had dried about an inch on top.

As above, about one inch of dry sand scraped away exposed the damp sand. Same settings/results as surface test.
<b>4. Also, are you noting when you dig targets that there are layers of black sand? So that the black sand is stacked like a cake as you go down through? Which will raise heck with the GB setting.</b>
Sometimes I can see some thin black sand layers, but usually it is thoroughly mixed in.

Sounds like target ID shift due to the black sand. I get positive target responses to empty holes on the beaches in Maine. I've re-posted below two pix from Maine beaches. First is York, very heavy black sand mixture, second is Ogunquit, more moderate but still plenty nasty. I've yet to see a single freq that will come anywhere close to handling them as well as a multi-freq. If your beach looks like either two, then a multi-freq may be your best answer.
