Users should be able to add in a swap what they want to offer, rather then only being able to ask for what they want.
Have a nice day.
Yes, in many cases and subconsciously, every collector knows which of his coins are duplicates- which he would prefer for exchange already given his focus. I did it with an additional notification of SWAP-for my partner that I also have these coins which I consider to be a suitable supplement for exchange.
I'll consider that a good idea.
Offering what I consider appropriate for the other party is also a sign of mutual benefit- the counterparty either accepts or rejects it, however, the possibility to draw attention to it and demonstrate it is reasonable.
Example:
Many coins issued by the National Bank are interesting and sought-after and may not be known in the world, but they will be rarities for collectors in the future - I have them in microtene bags.
When someone approaches me for an exchange, they decorate silver for 100 crowns and do not see the rarities, blinded by their vision of rarity-just a quick look at what was on top of the pile of Czech coins - an ordinary 50 CZK from the year 2014, but it is sold in different ways and here in the bags there are mostly rarities:

Or this nice example: check your collection if you already have this 5-haller? Those who don't have it don't know what Czech and Czechoslovakian numismatics are. ,, This is where our concept of supplementing the collection begins and ends,,

This is also what the collection is about, not just the accumulation of gold-silver and precious stones. This is also what the collection is about, not just the accumulation of gold-silver and precious stones.
