who cares?
I go out for the fun of it and the exercise. You might find a buried treasure, great, you might find clad, that's good too.
You need to just learn to enjoy metal detecting for what it is, and not expect to get rich off it, and not covet others finds.
When you time is right, you will be in the right place and find something nice, you can't force it, and if you worry about it too much it'll just make you miserable.
Finding silver is nice,finding gold is nicer of course, but don't become obsessed with it to the point where you miss the whole point of the hobby in the first place.
I was in your place many years ago, just new starting out, reading all the stories etc of everyones super finds, and every time Id go out and bomb it'd be like, god dammit, when am *I* going to find silver, or something really good...
Well years later, I have learned, if you sweat it, it won't happen, if you just go with the flow, be happy just to be alive and healthy enough to go detecting in the first place, it just happens for you.
Remember, this is supposed to be fun.
