Well, as far as older coins go, I found 26 wheats and one 50's Jeff nickel in one hole in the back yard of a house I've been searching this year. Overall, this house has produced 28 silver and around 175 wheats (also, 4 indians, 4 buffalos, one V, and various early 1900's foreign coins). It was/is a very nice house. I believe it started as a farm house in about 1880 (this accounts for the indians, v, barber dime as well as many flat buttons, suspender clips and crotal bells... these were all at about 6-8"). It then seems that some time in the late 30's/early 40's, the farm land was sold, and addition was added and a fairly affluent family moved in. There are 30's-late 50's coins EVERYWHERE. The best part is that they're all only 1-3" deep! Even better is that from the 60's on, the inhabitants must have been neat freaks, as there almost NO modern trash or coins. With about 225-250 old coins found, I've only found about 40 clad era coins and maybe 10 pulltabs. Its great. Now, my buddy Bernie owns the house and has given me free reign to hunt. I've put in at least 30 hours, and I'm still not done. Best... site... ever.
