I know they were supposed to be used for holding opium, but you rarely see them with much if any wear on them. and then other ones appear to be used as a locket. In addition, rarely do the die markers match up on these opium dollars and they look like theyre made from 2 separate coins. Here is the only worn example ive ever seen https://www.ebay.com/itm/1-One-Dollar-ND-Trade-Dollar-Opium-Box-Hinged-Dollar-Well-Used-/372815484984?hash=item56cd88d838%3Ag%3AzHkAAOSwAchdsc1T&nma=true&si=RO2L2cJqyoIU804dI25ZDl9D4Q0%253D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557 Here is another example being sold with the photo inside https://www.ebay.com/itm/034-OPIUM-BOX-DOLLAR-034-1878-TRADE-DOLLAR-W-OLD-PHOTO-NURSE-INSIDE-/353359650155?hash=item5245e05d6b%3Ag%3Aj6AAAOSwkMpgBy2b&nma=true&si=RO2L2cJqyoIU804dI25ZDl9D4Q0%253D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557 So whats the deal with them? Were they just lockets and story got changed over time? or were they originally used for opium and then became lockets? or was it all just marketing hype?
