Ok, that makes sense. I have mostly light and dark bley, white and black colored bricks. The bley colors were introduced in 2003/2004, and the black and white are probably the most produced colors, making it even more unlikely to get a pre-1985 one? But would the part ID (introduced in 1985), half circles on the underside of a brick (introduced in 2012), and other changes give me a clue about which era a certain brick is from? I found a picture where some changes over the years are described for a 2x4 brick. Does anyone know if they apply to other bricks as well in terms of the years they were introduced? (I am aware that the position of part IDs, etc., varies from part to part.)

Hi, I have recently bought some Lego bricks marked as "new" on BrickLink to build a MOC. I would like to ensure that I haven't received old "new" parts which could potentially contain cadmium. What I found out is that bricks produced later than 1985 should be safe. Would it be accurate to say that bricks with the LEGO text, part ID, and mold information (position and number) were produced from 1985/1990 until now? (This would be a pretty easy-to-spot indicator.) Does a higher mold number indicate that a brick was produced later? (I understand that a mold is used for several years and multiple molds are used simultaneously, so there might be some discrepancy of a few years.) I appreciate any insights or additional information. Thanks in advance! Best
