1964 Czech One Krona

So, one thing I love about world coins is they give me a break from the stress of trying to figure out whether barely-detectible doublings on my US coins are valuable or not. Just when I'm ready to throw all my stupid dead presidents off a bridge, I spy my case of 'foreigners' across the room, open it up and it's like, "Ahhhh," because nobody cares about minor errors like doubling in the rest of the (sane) world. But what if it's not so minor?
I discovered last night that my 1964 Czech 1 Krona has some pretty impressive doubling. The condition is not stellar and I don't think it's a key year, mintage-wise (kinda hard to tell; Numista lumps 1961-66 all into the 1961 figure; 147 million--I haven't yet seen mintage listed like this for any other coin). But just look how the planter has doubling along the underside of her arm, as do the linden sprig leaves. Kinda gives dramatic focal point to the act of planting it, no?
I'm thinking I'll post this as my first coin for sale on ebay. Don't worry; I know better than to expect jaw-dropping bids. But would anyone like to make a guess as to what she might sell for?
