Congrats! I found my first silver bracelet with my AT Pro last fall at a park. Found my first silver quarter with it last week.
Just being curious, what kind of a signal did your AT Pro give when you were over this ring? The silver bracelet I found was a repeatable and solid 67.
For me, gold/nickel/some aluminum rings in at a solid 53.
I have yet to find anything worthwhile in the late 50s through early 70s.
Pennies (zinc or otherwise) ring in 77-79. Haven't yet found anything older than a wheat to compare.
Clad dimes ring in at 80-83.
Clad quarters ring in at 85-87.
All silver finds for me have come in at 88+, usually into the early 90s.
Late 90s hits almost always turn out to be can slaw.
If you're getting a silver bracelet at 67, I doubt it's good silver. Might be plated or alloy. I feel compelled to mention that my ground mineralization is in the 75-85 range and that's probably why I get the VDIs I get for these metals.

This is the bracelet that came in at a solid 67. I just now laid it out on the floor, folded up in different ways, and ran my detector over it with the sensitivity all the way down. It was consistently reading 63-67. I also did this to a sterling silver ring that I found last year, it was a solid 80 every time. There is a good chance that the bracelet must be a low quality metal like you mention.
I get almost exactly the same numbers that you listed above. I found one of those new presidential dollar coins a few months ago, it was a solid 90 on my machine. Sometimes a badly corroded zinc penny will be in the upper 60s/low 70s. A 10k gold ring was in the 47/48 range, where usually I just find foil and other trash. I found a standing liberty quarter sandwiched with a buffalo nickle a few weeks ago, about 8 to 10 inches down. It was a signal in the upper iron range that bounced around a bit. Seems like the longer things have been in the ground, the deeper they are, and when there are multiple item together, the numbers can be way off.

This is the ring that I found last fall. It was a repeatable 47, and was only down maybe an inch or so I have never tested it to see if it is real 10k gold or not, so there is always a possibility that it is a fake. It is also the only gold ring that I have found since purchasing my AT Pro last October, so I have nothing to compare it to. A 52/53 is almost always a nickle, or sometimes a tab off a soda can. The soda can tabs sometimes bounce around to the upper 50s, which is usually a dead giveaway. The rings, coins, and soda tabs all pinpoint the same as well. The buffalo was on top of the SLQ, which was pretty much masking the signal of the SLQ. That's why you dig everything at an old homesite! Here is a pic of the quarter still showing the corrosion mark from the nickle.
Here's my ring finds since the beginning of 2012. All the gold rings are in the second photo. My rule with the at pro is to dig every signal between 45 and 65. I have found gold in this range. For the most part gold is a consistent number in this range and dose not waver much. There have been a few exceptions though due to trash or soil. I have severe gold fever and that's what gets me past the buckets of pull tabs and can slaw. Another bonus to this range is that I live in Murfreesboro tn, battle of stones river and find buttons in this range also. So I dig it all. Good luck.
