QUESTION ON LP


Dear all:
Recently I purchased one big-lot of LP and found something that's interesting.
It's not the normal type of 33 1/3 or 45 rpm that I used to know but it was something new to me. I tried search on Google but can't get a good result.
This type of LP is about 10-inch in diameter. Weights heaver then normal LP and also thicker. The material felt like "metal" but of course is not.
Would you please help me to identify this type of LP and on what type of turntable can it be play on. Also, is this type of LP worth anything (most of them are classical)?
Thanks a lot for your answer.
Happy listening
