Just a suggestion I posted in some other topic, Might go with your auction if you wanna use it, For your auction I think your minimum bid increment of .005 would be great considering the value is prob somewhere between .1 and .25(maybe more)
Just a suggestion for this auction along with other auctions regarding the minimum bid increments.
Considering BTC value is at 10k just to keep the round numbers.
If the value of a coin is in the range of $400-$500
If someone bids .05 BTC for one of the coins(Gold or Platinum) in this auction which equates to $500.
If you have the minimum bid increment of .005($50) it may be highly unlikely that someone will bid .055 since it's about 10% over the higher side of the value(collectible value plus the melt value) but it is very likely if you have the minimum Bid increment of .001($10) that someone who is even remotely interested might bid .051BTC rather than .055BTC. The idea with low minimum bid increments is to keep the bidders in the game at the last moment that keeps the auction fun for the bidders and the sellers.
Long story short, just my thinking better to keep minimum bid increments to .001BTC for items that are around .1 btc price range
This is purely what I think nothing related to this auction, I know we don't like to change rules in between the auction, but something to keep in mind for future auctions and if possible for this auction.
