The Japan Mint has started to accept mail orders for two sets of coins designed to commemorate the 35th anniversary of the popular "Doraemon" cartoon series.

One set contains a silver medal bearing a colored image of Doraemon along with six proofs of the 1, yen 5, yen 10, yen 50, yen 100 yen and 500 yen coins.

The Japan Mint, an independent administrative body, will sell 60,000 sets for 13,000 yen each.

The other set showcases the six coins in a special "Doraemon" case that plays the cartoon series' melody when opened. The mint will offer 200,000 of the sets for 2,300 yen each.

All orders must be made by Aug. 10.

Doraemon, a cat-type robot from the 22nd century that helps children with its futuristic tools, started as a magazine series 35 years ago and became extremely popular both at home and abroad, especially in Asia.
