  1. I found it detecting in a park.

    I tracked down a coin page where they were showing examples of coins stuck in commercial dryers between the two drum skins rolling around till it rolled the edges. So its possible thats what it is what they call a dryer coin. I just found it interesting that it weighed 5.66 grams which means it has not lost any material but it maybe could have compressed it turning between two drums which is why it is 1mm smaller than it should but still weighs the same.

    So maybe it is just post mint damage, sure looked interesting though. I'll probably put it into one of my books of odd coins where it will sit for the next few decades lol I'm new to coin collecting, metal detecting kind of got me into collecting now

  2. I don't think it could be ground off because it weighs exactly 5.66 grams still which is exactly what a quarter is supposed to weigh so it hasn't lost any metal.

    I did find on google examples of what they call dryer coins, coins that got stuck on outside of dryer drum in landromats rolling around and rounding the edges but those examples looked a lot more rounded on the edges? not squared

  3. Any of you coin collectors that can tell me maybe what type of error this is called and what it might be worth? It is a 2006 Nevada Quarter but it appears it was never struck with the reeds on the edges it has very high lip on both sides and measures 1mm smaller diameter than it should but weighs exactly 5.66 grams as it should. Its clearly not worn just not stamped correctly. I googled and couldnt find anything similar.

  4. thanks, yea I never thought of using the pinpoint mode like that. But yea this is  a particular park that had multiple schools on it in the past and large areas are just solid nails and you can hear every one of them every 3 inches lol

    But I have still managed to pick out a couple gold rings there so I will continue to experiment

    The best depth you can achieve with your Nox with respect to ground balance is when you’ve normalized your machine to the ground minerals in the area you’re detecting at. Whether that be at a value of -3 or 78, etc.....it depends on the minerals in the ground.

    I don’t like to do a completely “manual” ground balance...I prefer holding in the accept/reject button while pumping my coil up and down a few times (in an area of ground that is free of any ferrous/non-ferrous targets), and letting the machine arrive at a ground balance value after it has normalized the ground with the air.

    I also think it is more beneficial to “not” leave your machine in “auto-track” mode when you detect in highly trashy turf.....with auto tracking on, your machine will be trying to normalize the ground while the coil may be over a conductive target.

    I don’t use my Nox at the beach, so I can’t tell you if auto-tracking ground balance would be beneficial in that environment, but I’ve read it can be...with varying amounts of black sand at specific beaches

    Yea there is at least a couple  spots I still detect occasionally that you cant find a clear piece of ground to do a ground balance. I guess thats part of why I asked the original question about doing a manual balance. And I think your right in those situations I'm worried that Im not getting an optimal ground balance.

    Which is why I was trying to understand the "theoretical" part of ground balancing so I could better understand how to compensate.

    I understand that doing a balance for the ground your on will give you the best balance and thus depth in that situation. But does say -3 or 78 have any "theoretical" effect on depth or something. Im totally overthinking it im sure. I ask stupid questions like this with everything I do lol probably to make myself try to think outside the box or see if there is a  different perspective to look at my process of things.

     

  6. Ive read hundreds of posts about ground balance but what I want to get clarification on from Steve or somebody is this.

    When you say you mostly manual ground balance do you mean you just start at zero setting and just raise the number up till its stable? Am I understanding that correctly?

    Also, Am I right in thinking zero is the best depth in general an the more you have to raise it the less depth you theoretically get?

  7. oh wow, thanks for the info. I couldnt figure out how to narrow it down from the seemingly thousands of chinese coins lol mine measures 33mm diameter with my digital calipers so I can only guess it falls into the 32mm category? Also I notice that mine is struck off center, not sure if that adds any value ill have to find a coin dealer and ask I guess

    Not super valuable but an interesting find here in Oregon thanks again for the info.

  8. Im curious how the twist locks hold up over time getting dirt and grit in them? I am debating this shaft or the other one out there with the cam lever locks made by Detecting Innovations? But I dont think the Detecting Innovations one will rotate when collapsed to allow it to all lay flat into a case because they have a groove in the shaft to eliminate any shaft twist?

    The other benefit of the detecting innovations one is that it weighs a half pound lighter than the stock shaft. So im torn between the two but want to be able to put into a case for transport

  9. Should I try a different mode? This park is 200 years old and is all river rock everywhere ive dug so its hard digging anyway. But the river rock is natural. Dont think it was ever deposited by man. It runs along a creek that feeds off the main river. And its the main historical site for the whole city, the first pioneers to develop this part of the state lived on this property and their house is still there. He became the big bank owner in this city

    If I recall correctly, the Field modes are set up to be more responsive to low conductors, and that would include the pulltabs (at the expense of the copper items, etc.)  That doesn't mean that the Park modes (optimized for high conductors) would necessarily have given you a hint of the ring and Wheatie, but it would have likely had a better chance to do so.

    Lesson here, though, as you've pointed out -- trash (and those pulltab signals could have been gold rings...) can mask or in the least make it difficult to detect the desirable targets.  Given the time, cleaning them out is helpful to more than just the environment.

    Well and I am using the small 6" coil because of the density of trash so my thinking was that I needed more sensitivity to make up for the small coil to detect anything old and deeper than 4 inches or so? At least thats what my thought process has been? Tell me if im thinking wrong

  11. this same park continues to be relentless with the pull tabs day after day lol Another load of mostly old pull tabs and a copper ring and a wheat penny today. Im convinced there has got to be more good stuff here somewhere.

    The copper ring and the wheatie were both found in hole with a pull tab, nothing different in the signal than every other pull tab I dug so it was completely masked as far as the NOX was concerned and that was in Field 1 so the recovery speed is at 6 I think
