Hunting an old park from the 1920's with my CTX last week...Started running a grid pattern after digging some old wheats around an old hand pump put in by the WPA...I've hunted this park hard over the years with other high end machines...Received a good 12/45 high tone blending in with iron tones in Ferrous/Coin Combined mode I created...It pinpointed deep...I dug the target and pulled out a roundish chunk of iron...Placed that in my pouch...Rechecked the hole and got another good hit with the Garret probe...Dug a little deeper in the moist loamy soil and pulled a similar iron chunk...I was a bit disappointed until upon closer inspection I noticed a silver edge in the chunk of iron...I rubbed the edge a bit and noticed a second silver edge...Wow...I then pulled the other chunk out of my bag and rubbed that off a bit and again saw a silver edge...I pried the first chunk apart and it revealed 2 Mercury dimes sandwiched between 2 old bus tokens...The 3rd dime was also fused to another token...After carefully cleaning them with electrolysis at home, I tallied (2) 1925's, and a 1936 in the same hole...Not 5 minutes later I pulled (2) Indians in the same whole about 5' way...Definitely a great hunt...
