SecondHandLego Posted April 3, 2016 (edited) Recently, I started selling some of my second hand lego at bricklink.com. I happened to have bought a batch of second hand lego with some old parts in it going back to the early 1970s or late 1960s. On BrickLink I noticed there is an interest in these older parts. For example the ones with 'Pat. pend.' (Patent pending. Lego applied for patents in different countries as of the late 1950s or earlier) inscribed on the inside, or the ones that have it erased with a small 'blob' (after the patents were granted). Also the location of the molding 'pip' is apparently telling for the age of the brick and hence of the value of it to Lego collectors. Such markings are of couse very handy to estimate the age of a brick. However, I noticed that there is a more detailed coding scheme in the bricks that seems to identify their respective molds. It consists of letters and numbers in various coding schemes and locations on the bricks. I'm sure you know what I mean. (but if not have a look here https://frankvanderm...-of-lego-molds/ Interestingly, while going through a batch of 'Pat. Pend.' 2x3 plates, I noticed a few funny mistakes in the molds. Apparently, the images are too big and have been removed. Check the above mentioned link to see one of them. It seems interesting to me to have a chronology of the different molds (and colors), at least for a number of often-used bricks. I tried to find it through Google but could not find anything. Does anyone know of such a chronology? Would you be interested in having access to it if it existed? Would you be interested in collecting the data?

xboxtravis7992 Posted April 3, 2016 Colorwise there is a Flickr page that details Lego color history, but I can't recall it's name. Moldwise, I don't know. New Elementary covers new bricks, but doesn't have a mold history. Share this post Link to post Share on other sites
Ecclesiastes Posted April 3, 2016 I deleted the pictures,because they were too large. Please re size them to 800x600. Share this post Link to post Share on other sites
SecondHandLego Posted April 3, 2016 Hej Ecclesiastes, sorry about the pictures, I thought the rule applied only to images hosted on the eurobricks server. PS no offence, but I am not going to resize them. I've spent more than enough time on them already. Next time I'll take the size into account. Colorwise there is a Flickr page that details Lego color history, but I can't recall it's name. Moldwise, I don't know. New Elementary covers new bricks, but doesn't have a mold history. Thank you for that, xboxtravis7992! I found this one after your pointer to limit to flickr. It also maps the different color codings and namings from TLG, BrickLink, LDraw and Peeron. http://www.ryanhowerter.net/colors.html Share this post Link to post Share on other sites
