Detecting Location Raises TID Question

[mapper65]

About two years ago we were give permission to detect a private park owned by a fraternal organization. They purchased this park in the early 40's and have never let anyone detect it. The park is table top flat and about the dimensions of a football field.

The first day that we were there I found about 110 coins. The second day about 130 coins. This place was polluted with coins. I stopped there on Saturday and found 44 coins bringing my total finds up to 435 coins. With what my Mom and my brother have found we have about a combined total of about 700 coins.

What's really strange about this location is that I have a decent handful of wheats that I've found along with many other pennies and nickels prior to 1965 but I've only ever found one silver dime and it was a 1964. When I was there on Saturday, of the 44 coins that I found, about 8 were from the mid to late 60's but again no silver. I found a 65,66,67 & 68 quarter, a wheat and a 65 dime.

I had a minor revaluation the other night and wanted to run this question past everyone. I hunt in a pretty open mode. I only have -8, -6 & 48 discriminated out.

I guess my questions is.....does anyone ever find silver coins with an ID of 48? Anytime I've found silver it's always been between 38 & 44 and air testing also gives me that same range.

I'm kind of on this place with a vengeance to find some silver because I have to believe that it's there but for some reason I just can't find it. I've used HF, MF, 10.5" & 6" coils. Just can't figure out why this place doesn't seem to have any silver. Let me know what you guys think.

I guess that would be a head scratch-er after 700 coins.Could be they let nobody detect that THEY know of...
I hunt 4 tone all metal 98% of the time....I agree on the dime TID...The 46/48 Tid I got just the other day was a 74 Kennedy.Would have to wonder what the digger coil would do for you?What coil are u using...

I NEVER notch out #48. last year I found 13 silver half dollars and a total of 36 in the past 7 years. Not all come in that high of a number but some do.

How deep are you finding the clad coins??? also is the soil on the mild or hot side??

Since you have already pulled out over 700 coins and you have already used the 6" coil and still no luck on the older coins. I would say masking is not your problem.

I'm finding coins anywhere from 2-6", sometimes a little deeper. The soil appears to be pretty mild.

I spent the first few days using the 10.5" HF. After I felt we had it picked over pretty well I switched to the 10.5" MF. After that I used the 6" HF DD. On Saturday I went back to the 10.5" MF. I seem to get a little better depth with that than the HF version. It took me a two to three hours to find the 44 coins the other day.

I kind of doubt that this place was ever detected by a rogue detectorist. It would have been too hard for them to pick out silver coins especially since we found nearly hundreds of quarters, wheats and dimes which would have been very close to the same ID as something sliver. When we first started you couldn't go 2-3' without finding a few coins. It was as if it had rained coins at this location. I may be underestimating at 700 coins.

It would be interesting to see what a 3kHz coil could do there. It would hit on edge coins harder, and likely hard enough to get your attention.
I'd personally go back in with the 7.5kHz 10.5" and go slower while overlapping more.

 

[Mark in S.E. IA]

That's not a good thing that your finding clad down 6" + and the soil is mild. Places like that it's real tough to find the deeper silver coins.

Since the soil is mild I would try the stock 9" CC coil. It's better suited for mild ground and like Longhair said, go super slow, overlap your swings and keep your coil as close to the ground as you can. I would say a 4 second swing speed or even a lil slower. Also I hope your wearing headphones because the deep silver is going to be a faint whisper in that mild ground.

Since I only use the 10.5 MF DD coil here is what I would do when using that coil in real mild ground.... find your GB number and then push the "+" key 2 to maybe 3 times and run with that GB number. Some times setting my GB that way in mild ground when using the DD coil has helped me to get a stronger signal on the deeper silver. Oh yea, Max out the Sen too.

good luck

Sounds like a few sites I've done over the years and still return to-every once in a while. Good amount of weathered clad, enough wheats to keep me coming back and a single silver (usually a dime from '59-'64). Can think of 6 off the top of my head.
Here's the depth pattern for most of them:

Wheats - majority 3-5" other cents 3" or less
Clads- surface to 4"
Some anomalies in depth- but enough uniformity to call it a pattern.
Depth patterns etched in memory with a Whites analog (accurate depth on coins) and recovery.

Return with the 705-various coils--depth reads different-but recovery shows the same pattern.

Too many coins to have been worked over. Too many good signals in the "silver layer".

Long winded-might just be one of those places.

I went back to this site today and spent about two hours there. I decided to use my 9" stock coil which is the only coil that I haven't used at this location. I was beside myself as I looked at the dates on each coin that I pulled out of the ground. Here's why.

I found 19 coins. 1 quarter, 3 dimes, 1 nickel and 14 pennies. Of those 19 coins, look how close to silver I was.

1964 Nickel

Pennies
(1) 1967
(2) 1965
(5) 1964
(1) 1963
(2) 1961
(1) 1960
(1) 1959

So of the 19 coins, 10 were during the silver era and 2 missed by a year and 1 by 3 years. I just can't understand it. This makes 454 coins that I have personally found at this location not to mention about 300 more found by others in my family. Still the on,y sliver has been the 1964 dime that I found.

I have a feeling that site didn't see any action until the late 60's to early 70's and your not going to find much for silver there. sorry

 

[mapper65]

I have a feeling that site didn't see any action until the late 60's to early 70's and your not going to find much for silver there.

It could be, I'll have to ask the guy more about the property. I know he said they bought it in the 40's but that was all that he said. You would think that if I'm finding coppers and nickels from the 40's through the 60's that there would be silver. Who knows.......

I'm not done yet but but not sure how many times I'm willing to go back. Just kind of one of those places that is easily accessible so going on a whim is no big deal.

 

[Mark in S.E. IA]

In the 60's and 70's it was common to have a wheat in ur pocket and the nickels from the 40's and 50's nobody collects them except for the war nickels so in the 60'sand 70's I'm sure it was common to have one of those years in your pocket too.

Good thoughts from all. See my previous post- might just be one of those sites. Of the 6 sites I was referring to -1 was a school from the '40's & one from the '20's. Some have suggested that the land was filled and leveled. Soil does indicate such---BUT other places of similar discription give up silver. You can even see the different colors/layers of soil when you reach a deeper older target.
As Mark stated-coin pattern from '65 to the '70's.
My sites are also easy & close. (other side of Pa) I still go back when I don't have time to go anywhere else. Some for 30yrs. Figured my 705 would come up with something deeper -at least at the '20's school. Zero....

 

[mapper65]

The only thing that I can think of is that this guy was wrong about the property being purchased in the 40's or maybe they bought it the 40's and didn't actively use it until the early of mid 70's when people knew to hoard silver.

It's been a fun and easy place to detect so I guess my new goal is to now see if I can personally top the 500 mark for coins found at this location.

Based on this information I decided to open up my #48. I noticed a lot more high signal chatter once I did that. I also opened up #6 to see what I've been missing.

 

[mapper65]

Same here. I turned off 48 again while we were out yesterday. I'll take my chances on missing something.
