Complaint Review: republic jewerly

i am in the process of selling my coin collection and was looking around and started calling places  as i have bought some coins from republic  and then decided to sell them  my chin hit the floor when they told me how they buy the coins

the look in the grey sheet ( which is the dealers  bid/ask) prices for coins  and when i called them to enquire  how thy bought coins they said

we go by the grey sheet  and then from there we discount the price by 50%
so to say if you have a morgan dollar valued at dealers price or asking/bid price of 70 dollars they will give you 35 for it
this is one of the biggest rip offs i have ever heard and i hope anyone reading this take this warning  and not do business with them a total rip off
oh and  then to sell my coins  you have to make an appointment and get this they charge you $50 to estamitate  coin collection and if you decided not to sell them the coins your charged  $50
if you don't believe me call them and ask for your self if they buy coins and  what percentage off the grey
bid/ask sheet they discount the coins
a total ripoff  take it from me
