Hunting an old church again in Bucks County, PA proved to be a worthwhile adventure.  I have been hunting the church grounds for the last 20 years but thought I would give it a try with the White's XLT.  The 1878 seated dime and Indian head pennies (1887, 1893) were all 4 1/2" deep.  The dime actually gave off a half dollar reading...I think because of overnight heavy rain.  The wheat penny is 1914.  The object on the bottom right is a Clasp Eraser (holder) made by the Eagle Pencil Cos.  The Pat. date is July 20, 1886.  The object top row right is a rivet from a harness or reins.  Part of the leather is still attached.  On January 8, 1987 I found an 1890 seated Liberty dime at this same church.  It also was 4 1/2" deep.  The Indian head pennies never gave a true penny reading on the VDI meter.  Anywhere from pull-tab to around 60 is where they hit.  Always dig pull-tab readings at 4 1/2" when detecting in an old church yard.
