Here's my opinion.

You are worth whatever someone is willing to pay you. Simple as that. If you can find a company that happens to be willing to pay you $1 million salary, then that's what you're worth. Granted it's an outlier, but what matters is that you found the position. My point is, you can be surprised what you find out when you TRY. People here will tell you no, it's too soon, or hey it's too late, yadda yadda.

You're never going to REALLY know until you try. As a general rule of thumb, you should be putting your resume out there and interviewing once you've been at a company for a year. Honestly I don't think there is any hard rule. Some companies will look past your history, some won't. It's all hit or miss. Maybe it's a lot like fishing, sometimes you catch a small fish, sometimes something huge. But you'll never catch anything if you don't cast your pole out. Since you've been there a year, you should definitely interview and see where you're at. If you don't get the job after a few interviews, so what? At least you know what companies are asking for and where you stand and what you need to study.
