I recently purchased a handheld tool with a camera on the tip. It came with 3 attachments including grabbing "fingers", a hook and a mganet - it did a similar job but in another vehicle I have. I know it may be a overshoot for just removing a coin one time, but since I have 2 kids I am guaranteed to have similar situations in the future so I bought it. It makes job easy as you can see where tip is going and where foreign object is located
Similar to this, but I have different brand:
