setting up coin programs

[Anonymous]

Just a little information for anyone setting up a coin program or wondering where to look for the cursor on dimes or quarters. 1796 to 1830 draped bust quarter. weight 6.74 grams composition 89.2% silver 10.8% copper diameter 27.5 millimeters. 1831 to 1837 identical except for diameter of 24.3 mm. All quarters after this date are 24.3 mm in diameter. Liberty seated 1838 to 1873 6.68 grams weight 90% silver 10% copper. 1853 only 6.22 grams weight. 1873 to 1891 weight is reduced to 6.25 grams up to 1965. Composition is 90% silver 10% copper on all up tp 1965 or clad. These include all barber, standing liberty and washington. Clad 1965 to date weigh 5.67 grams contain 75% copper and 25% nickle. Bicentinial have small silver content. Dimes are as follows 1796 to 1837 weigh 2.70 grams are 18.8 mm in dia. and are 89.2% silver and 10.8% copper. All dimes from 1837 to clad are 905 silver and 105 copper and are 17.9 mm in dia. 1837 to 1853 weigh 2.67 grams. 1853 to 1865 weigh 2.50 grams. All clad dimes weigh 2.27 grams and re 75% copper 25% nickle. If you have one silver quarter washington, barber or whatever it should come in at aproximatly the same position except if it is highly corroded or in high mineral soil. Same for dimes. Because of slight variations in weight or diameter you may notice slight movement of cursor to left or right of normal but not too much. Indian head pennys come in in two different locations due to metal composition. Flying eagle and indian head through 1863 are copper nickle composition and will hit in aprox same location of cross hairs. 1865 and a few 1864 are copper tin and zink and will hit in different location.

I have not been fotunate enough to get my first silver. I run with no iron mask so as to see and hear all targets. If I was to hit a potential 89.2% silver target wear on the smart-screen would it hit?
Say on the top left?
I understand you are new also, but what have the pro's said to you?
Charles of NY months ago gave up a good site here in Washington to look for old coins....but it's 180 miles away one way. So anyway to get the oldie's near me I need to travil some distance and I'm not able to do that right now.

Johnny. On my explorer they hit in almost the same spot as clad. Have only found one barber, but a bunch of old washington 90/10 silver quarters and they hit almost identicaly in the same spot. I have a friend who is a coin dealer and he gave me the opportunity to test nearly every different coin available, some old and corroded and they all hit near the top right of the screen. The only thing I know of that would make them hit elsewhere is heavy corrision or highly mineralized soil. Hope this helps, lilfox.

Johnny, A couple of more things I forgot to add. The slight difference in silver content, less than 1% should not make much difference, diameter is where you will find the big difference as between a dime and a quarter with the same silver content the dime will read to the left of the quarter. Also because most of the time you read conductivity a nickle/copper clad is nearly identical to silver, with a very slight difference in induction. I have heard of a few people finding barber quarters on the left side of screen but I think it is due to corrision or mineralization. I have found that a coin program is ok to run but you will miss a good number of coins by doing it. Lilfox.

Hi Lilfox,
I think the safest way for you to hunt coins is to ignore the cursor and its position and concentrate only on sound. I have found barber dimes and indian head pennies with inaccurate cursor positions. I saw the cursor registering iron but heard a signal indicative of a good coin hit. The only time I trust my cursor is when I stick my X1 target probe in the hole and get real close to the target. Then I know for sure if it is something worth digging. If it is iron, you get hardcore nulling. If it is silver or copper, the party bells start ringing! Actually, if it is iron, I dig it anyway and then recheck the hole with the search coil to make sure I wasn't actually hearing a nearby coin. In the perfect scenario where the buried coin is isolated, is not near any trash, and is from 1" to 6" deep, I think the cursor will be accurate. But in the realistic park scenario there are several factors that will many times cause the cursor to be inaccurate. These factors are: nearby trash targets, great depth, vertical coin orientation, and mineralized soil. Good Luck!

I agree with you Mike. The post is just a reference for anyone wanting to air test or set up a program. I do occasionally use an old coin program but edit it to -12 with large cursor as coins will hit on the screen in strange locations. Like you I rely on tones about 95% of the time as it is the best indication for silver for me although I do have a problem with I>H< pennys. There I do tend to use the screen more than usual because for some reason no one finds to many I.H. pennys in my area and I do not remember the tones to well. Thanks for the post and HH. Lilfox
