It depends when you bought them
the market has fluctuated an awful lot in the last few years and some ponies have really dropped in price. Also a pony is only worth what someone is willing to pay for it
if you really wanted them and love them, then it's ok to over pay
I have also found that Facebook prices are quite different to MLParena and eBay prices
I did a more in depth search for you
Furga $300-400
Brown Italy Butterscotch $60-400!!!!!!!!
Perla $450-600
I hope someone else can chip in with prices
Love pkw xxx
