Recently I've noticed that when you go to add more coins to a swap pre-existing you can select the same type twice, also mentioned by Phil; it would be great if this could be fixed - it's especially awkward on large swaps lol. Also the wish list.. I think that once you get that coin it should maybe automatically knock that one off.. I recently added loads of coins to my wish list just in case some members use it, although I don't think most do, I don't.. Generally anyway just a few suggestions to make things a bit better. However I also agree that everyone has different views and that if you implemented all of them it would be a mess, and there's also the fact don't fix what ain't broke !
I think it would be good to let you know if you're about to select the same coin. Many collectors collect by year so getting rid of the same type wouldn't work for them. Also there are some collectors out there who are interested in multiple copies of the same coin (maybe their family collects as well and they are just getting a copy for them). Just my opinion.
I made the same mistake recently. I went to add more coins and chose the same coins again, thinking that I had missed them previously.. Then when I saw they were duplicates, even though I could uncheck them, they still remained on the swap page. I agree there should be a marker on coins you've already selected or a notification that you already chose them.
