[QUOTE="Theodosius, post: 4432905, member: 77077"]Hard red and blue deposit don't usually indicate bd. Pink crumbly deposits are often what is left behind by the bd action. Something to remember is that bd is only active when the humidity is over 50%. A coin stored in a dry place can look fine until exposed to more humidity and then you get the bluish green blossoms. Like when someone ships it to you from a dry region. Coins bought from good sellers are less likely to get bd than random eBay sellers who may be using pool acid to clean their coins. ☹️ Note that there are great eBay sellers and awful ones and feedback means nothing.
