Indian head pennies and early wheaties. Gold rings. Depth is usually the giveaway on the older pennies... depends on your area, but a 5" zinc signal is usually an old penny for me.
I find that most of the zinc items i find are in the 50 to 62 on my VDI. zinc lids, small
bottle caps , toy cars, ole wheaties, some auto parts come in this range also..
Strangely enough, in my area of East Tennessee, I have found some gold, silver and even some brass or lead relics read like a zinc penny!! Just proves this hobby is a LOT like fishing, you can't ever tell what you'll pull in!! Good luck and great hunting! Regards, Richard.
Tony24, see what we're saying? I.D.'s are great as long as you don't get hooked on just what the display says! Combine the sound and the meter and after a little learning curve, you will be surprised by what you could have missed! At1cad, great Indian! most of the ones I find in crop fields are really beat due to fertilizer! Good find!! Great hunting and good luck!! Regards, Richard.
