Petespockets55 - You definitely had the count to value ratio pegged. Did you base that off your 'jug'?
Yep, just me over the past 3 years (sort of a semi-hobbyJob). But in all fairness, not necessarily same number of holes. Handful on the surface and 10-15% of holes had multiple coins. Given your fondness for analytics and detecting, you may have interest in some of these assumptions:
On distribution:
- Cents (coloration): Brown (mostly), blend in to most surfaces
- Dimes (size): Smallest so tend to slither to floor easily. And, out here we are primarily conifer needles, fluffy year 1 but decompose quickly.
- Quarters (weight): Given size, it is surprising to find so many. Assumption is weight drops them to floor quickly.
- Nickels: Just an outlier. The signal is the same as 22 bullet casings; in my neck of the woods we have a lot of bullet casings. Unless a signal is rock solid it tends to be ignored (even with that it is a 50/50 outcome)
I'm anal, GPS of each good find goes into Google Earth. Jewelry and other collectible relics aside - out of that 2-Gallon jug and rejects (roughly 6K coins), the following were processed.
Cents - IHC (17), LWC (Don't track but guess 125-175 range is fair)
3-Cent - Nickel (1)
Nickels - Shield (1), V (21), Buffalo (16), War Nicks (8), Pre-60's Jeffs (Guestimate 10-15, don't track)
Dimes - Seated (2), Barber (26), Merc (31), Roosie Ag (33)
Quarters - Barber (4), SLQ (1), Wash Ag (13)
Halfs - Seated (1), Barber (2), Walking (4), Franklin (1), Kennedy Ag (3)
Dollars - Morgan (4), Peace (1)
Obviously #'s are heavily skewed towards location researched/targeted. For example, currently working area that is 30's - 50's collectible coinage only.
Out of the roughly 300 isolated I'd estimate 50% conserved well enough to add to collection or sell. Only 5-10% of coppers ever get beyond cull. So somewhere around a 2-2.5% collectible recovery rate.
I swing a metal detector and have a knack for finding dirty old coins.
