I would not recommend that any coin collectors list their decent coins of value, on here, as an auction. Either the buyers have no idea of the value of these coins or they do not know the value of an INK. I have recently had several auctions ended with bid that did not even come close to the value of the coin. Currently $1 USD = 596.13 INK. $20 USD = 11,910.71 INK. An Ink is worth much less than a penny and is very volatile. It bounces back and forth every few days. There are a few god sites to check the value of INK Protocol: https://www.coingecko.com/en/coins/ink-protocol/usd Also a good conversion tool is https://design.stanragets.com/listia-xnk-helper/. Both sites will tell you the daily value of INK Protocol.
