I am slightly stumped to the value of coins/trackables that can be taken ...but what to be left as a swap? Ok toy car = toy car easy enough
to work that one out or little kid stuff for little kid stuff...
But coins etc have me confused as new to this, but, after looking to see what they retail for to buy ..do you leave an £10+ item in the cache if you take a coin /trackable that is going in the next cache it fits in?
