When I joined this website, I'd thought that swapping or trading coins and notes here would be foolproof and free of worry. However, this is somewhat shocking to be cognizant of the fact that it is the complete opposite. A new member has to send out their item first without any guarantee that they'll get what they're looking for; or worse, their own item back (not to mention the cost spent on courier and time wasted waiting for it). There have been a number of issues (as complained in the feedback) with members losing their items, even though it's a small percentage of the total numbers of swaps, it's still highly unfair to those who lose their goods (some of it being quite valuable), be it the postal company or a member with dubious intentions.
So, my question is, is there a sure way to exchange items without the fear of losing them? Doesn't matter if it comes at a cost; it will be, at least, reassuring and totally worth it.
Numista should have initiated a service at a fee, through which all members would send the items to a Numista's location. Upon receiving the items from both sides, they would then redirect them to the respective destinations. If one member does not send theirs, Numista would return the other member their item.
I don't know if they'd like to be bothered about it but it's not a very favourable situation for members, aspiring to make trades.
