two options for you.

Ambank - The one at my area has a self service coin counter machine. It seems to auto deposit to your bank account. I never use it before though, so i dunno if there are charges for it or not. or how is the process like.

Aeon 1 Utama - They have a coin counter machine at Aeon GF, near the customer service. You put in all the coins and it will auto calculate for you. In return they will give you back the exact amount in Aeon voucher. I used this one before. no charges. Only use this if you sure you will be using the vouchers to shop
