In past 5,6 years I did not exactly had a experience where some one stolen my banknotes but I do have couple of bad experience where some collector did not fulfill what they promissed to me and sent AUNC or XF grades instead of UNC.
I recommend all newly banknote collectors to search on internet with the name they are going to trade. Most probably they will find the required information.
Here are some tips which helps you to avoid any possible bad experience:
Take some time before you should reach on a deal with other collector.
Be honest and treat other collector like what you like to be treated.
Beware if some one offer you amazing or a deal which is almost impossible.
Use only registered mail.
