I just received a swap request and none of the coins selected were in my swap list. Also they are not in my collection. It also happened about a year ago but not since then and I have had many swaps.
Hello Sim,
I just checked the swap. I see the swap was opened on March 22nd with 7 coins selected. All these coins were removed from your swap list yesterday shortly before you posted this message, so they were still on your swap list when the swap was opened. Two of these coins were added to your swap list recently enough, so I can provide the date when they were added, in case it helps.
