If you are stuck on running a coin program I would use the stock coin program the Explorer came with.
This program is a COMPOSITE of hundreds of coins from around the world according to Minelab
Although I would not recommend that to anyone EXCEPT a new user for say half a season or until they get a serious grasp of the tones.
You can use the Edit feature starting with a blank screen and by using the cursor move it around to any area you deem and set up the Explorer to discriminate out anything you would like by notching it out (blackening).
When you are doing this the cursor size can also be changed making it a quicker task BTW.
You could even use the "Learn" feature. Basically notching in the coins you are after (there are 1024 notches) BUT, remember not all coins are laying flat nor are they the same thickness as when minted.
Ground mineralization also plays a part in this and many are at greater depths effecting their distinct screaming high tone and the hit on the SmartFind screen.
I would say many of my coins would not hit realistically where a learned coin might hit.
This will drastically throw those hits outside of your accepted coin target program and exactly why I would not suggest making one.
To sum up coin programs:
DO NOT USE THEM if you are truly after the deepest oldest coins IMHO.
That is why you need to learn the Tones and use the SmartFind screen as a reference and not the reverse.
Also, as far as getting carried away with discrimination:
Have you ever wondered where a Buffalo Nickel and a Barber Dime hit in the same hole?
How about a fatty Indian and a old Silver?
Are you willing to set up all these scenarios and the countless others which may include a coin?
Now imagine these scenario's and these coins canted along with the other scenarios already mentioned.
There are a so many variables you are going to probable discriminate out if you are going to just go after exact specific coin hits.
The more discrimination you have the more you are going to be missing things pure and simple.
I suspect the reason you have had little response to your question is answered above.
In short I would surmise most Explorer users in the U.S. (well except maybe those guys on the other side of the pond with their varieties of Bronze ancients
) do not use a discriminated coin program looking for specific coins.
I like my IM set at about -14 / -12 and sometimes will run it wide open with no discrimination at all.
I would suggest you try "Ferrous Tones" as this will basically give all your highest Conductive items (Silver, Copper, Gold) and (lowest amount of Ferrous content) a higher sound and your less conductive items like Iron (which is Ferrous) a lower tone.
But, once again it is only a suggestion but, trust me well worth a try.
You can search "Coin Programs" and search the Classroom or reg Forum also setting the time-frame to "all dates" but, many pictures are no longer there but, the posts are.
Thought I would at least respond to your question even though I could not provide a special coin program.
