Need some pointers

[indianainsulators]

After finding glass shards in my garden, I started doing a little digging, and have found some very interesting things already.
Most notable is a complete lid for a butter churning crock, and a spark plug I was able to date as pre-1930.
I've found the bases to approximately eight Ball jars, and the base to a Kerr jar I was able to date as 1915-1920's.
The thing is, I've only gone approximately 8 inches deep, and the hole is only maybe 5ft by 3ft.
I don't want to tear up my whole yard, and I don't have the tenacity to go ten feet deep unless I know there's a treasure chest full of gold waiting at the bottom.
How do you guys know when to stop? Right now it's confined to my garden, but I've already got half of a 5 gallon bucket full of glass shards.

You stop when the ground stops you, or you run out of will/steam.

Look into a probe and or metal detector, so you're not just digging random holes all over the place?

I've metal detected for a while, you should invest in one, I'd get a garret ace two hundred for around
$200, they're really nice for the price

My four year old niece found this one in the garden today. Diamond on the bottom and all that is visible of the main embossing is "S."
Is this the same Diamond as the insulator manufacturer from Canada? (Dominion)
How old might this be?

with out a top hard to date but I would guess pre 1920, but just my opinion, others may vary? Leon.

I decided to clean and sort everything I haven't yet photographed and shared here.
First, pieces were sorted by color.
Then, whether or not it had an embossing.
Finally, is it in any other way it is identifiable, and/or notable. i.e, does it stand out from the rest of the shards.
These are just preliminary pictures, I will go back and get better pictures of the "unique" pieces later.
Again, these photos do not include the pieces I've shown previously in this thread. So, for some of the better pieces, scroll up.
Everything I've found is still suggesting this dump is 1920's vintage.

My neighbor is 80+ years old, and has lived in this area all her life. Her parents actually used to own the land I live on now. When I asked her if there was anything there before my house, she recalled a small old house that her parents had torn down many years ago.
The oldest map I could find for this area was 1942, and it shows two structures of some kind on the property.

I miss getting all excited and not being snobby about what I keep..
I have re-buried, thrown, or shot 100x what I've kept.

I don't know what the hell you'll do with all that, but good for you!

I'm more of an insulator collector than a bottle/jar collector, if you can't tell from my profile and other posts. So something I found on my property is worth 10x as much to me than a jar for sale on eBay or at a show. (Unless it was made by an insulator manufacturer.)
If I found this same stuff at a public dump, you're right, it'd go right back in the hole. But this was in my yard, so it's sort of special. My wife suggested making stepping stones out of the jar bases; I think that would look neat. And as for the rest, I've sorted it out by color, so I've got a jar of blue aqua glass, a jar full of clear glass, and a small glass display box for the "other" stuff. I just got a building delivered that I am converting into my little insulator museum; I plan on just putting these up on a shelf in there. It doesn't take up much space.
