10 Auction Rules & Info

1)   NO RESERVE - All auctions start at $1 with no reserve.

2)   END TIME - Auctions always end on Sunday between 4-7pm Pacific Standard Time. 

3)   VERIFICATION TO BID - There is a one-time verification fee of $1.00 to activate account. Once paid, your account can bid seamlessly on all auctions without ever having to verify again. This is not for us to profit, it is a small charge simply to protect our community and validate bidders. Integrity is our #1 priority at Mineral Exchange, this is why we choose to verify our bidders when many others do not. 

4)   SALES TAX - Sales Tax is not charged on bullion/numismatic items unless you're a resident of California and invoice is under $1500. 

5)   BUYERS FEE - MX's standard 10% buyers fee is added to winning bidder's invoice. All auctions start at $1 with no reserve so please take this into consideration when setting your max bid. 

6)   SOFT CLOSE -  Due to complaints about "bid sniping" we have incorporated a "soft close". Soft close will only activate if a bid comes in the last 60 seconds of an auction. If no bid is placed in the last 60 seconds the auction will hard close at normal end-time. If a "snipe" comes in the last 60 seconds the auction will extend one-time 10 minutes more, then hard close. This allows everyone a fair chance to set their max bid without being sniped. 

IMPORTANT NOTE: Please make sure to click refresh on your browser when auctions are closing, especially in the last minute. This will give you the most accurate current price as sometimes our site cannot auto update

7)   MAX HIDDEN BIDS - Any bid AT LEAST 2 minimum bid increments above the current bid will deploy your max hidden bid. Please note that minimum increments move the current auction price regardless if you are the top bidder. If you want to set your max hidden bid it needs to be 2 or more increments higher than current price. 

-When you're top bid it will say so with GREEN font. If there is an underbidder with a higher max secret bid the font will remain RED and you will be notified that you've been outbid via email. It is good practice to refresh your browser after placing bid to double check whether you are the highest bidder or have been outbid.  

8)   REFRESH BROWSER - If you have already set your max bid you do not have to worry about this but if you want the most accurate current bid especially at the end of the auction it is important to keep refreshing your browser. Auctions are always spaced 1-5 minutes apart to give you time to be able to set your max bid. 

9)   SHIPPING - Mineral Exchange currently only ships to the U.S. and uses USPS priority or Express Mail with signature confirmation. You will receive a tracking number within 48 hours of cleared payment.

10)   INVOICES - Winning bidder will receive their invoice via email they provided to make account. Please make sure to check spam folder in your email if you do not see in normal inbox. All invoices will be sent within 24 hours of auction end.
