You make hasty conclusions and it is a shame to me that without any reason you express a negative in my direction ....
Why don't you say how much it costs in Russia and explain how much you would like to sell it for abroad?
You're definitely at the wrong place if you think someone would pay more for something with a fixed price. If you don't want to say how much each coin costs, you need to at least name each coin, its year and how many there were in circulation.
Sir, I call the price of $ 500, because sending abroad will cost a lot.
On each coin and banknote the year of its issue is indicated.
