Hi

I have recently been offered an 1875 Queen Victoria 1/4 Rupee. The Coin is in A-UNC condition, a fabulous piece.

Unfortunately my standard catalog of world coins for this period has been delayed in the post and am limited on time (i have until 6pm tomorrow).

Could anyone advise me on a catalogue value for this coin???

Also available is an 1893 Argentinian "Dos Centavos" in excellent condition with retained lustre (would grade approx EF). Any help on a rough guide price for this would be appreciated too!!!

Cheers

Richard

P.S He also has a coin which i know nothing about....It is a "Carolus III Hispanarium" coin of 1765, and measures approx 9-11mm in diameter, silver, which is again in excellent condition.

Can't find this coin anywhere, so any advice on what it is along with an estimated value in min VF condition would be appreciated.

A tricky one in know, but i'm sure there's a genuine expert out there!!!

MANY MANY THANKS
