Number of coins for exchange??????

I am looking for collectors to exchange coins with but am left totally confused when I actually get to their swap list. Below is an example only and does not bear any resemblance to any collector.

The collector has 200 coins on their swap list, which I feel is worth investigating only to find the list contains only 10 different coins, by KM#. The variety is actually in the dates issued, or the fact that there may be 50 of exactly the same coin.

Surely, something can be done to differentiate between the actually number of different coins available to the total being offered for exchange.

I’ve seen this with banknotes also. Often the banknotes for trade are entered as undetermined which is frustrating for those of us looking for specific dates or signatures. I just pass them off as scammers as many never respond to questions about what they have.

Mmmh…it works for me exactly like you propose:

E.g for you, when I go to your profile, its says:

Their coins or banknotes that may interest me: 150

Then, I click on view swap list, filter for coins that I don't have yet and it says there are 200 coins available.

So, 50 of them (200-150) are the same KM (just different years, or multiples of the same)
