Looking for light toned VF/VF+ suitable for scanning for Lanka Coin website.
I probably can't afford the higher grades particularly for the coins which have higher numismatic value, and probably consider VG/F for these coin.
No Coins have been purchased with numismatic premium over US$150, and under 20 coins above US$50.

For coins I need for this collection I am interested in
purchasing at prices about 80% of Krause, typical of prices I have been able to
buy on ebay, the Internet and at Local coin shows.
or trading equal value using Krause prices,
I have a reasonable collection of extra Ceylon coins both recent (high grade) and ancient (lower grade).
