Business card critique

Hey everyone, I sell some stuff online, mostly collectibles like pokemon cards, soccer stickers/ cards, coins and banknotes. Currently I'm starting to expand to iron, sewing machines and other stuff that I find for free or very cheap, but more mechanical than technological. In addition to this, I'm not full time, I'm only doing it part time, so I would like to have some business cards to give when I'm at car boot sales or garage sales, something simple, but at the same time neat, so people can call/ message if they have some stuff to move.

I made already a few models, but I'm not sure if they are adequate or not, can you help me out by any chance? The first models don't have my location on the back, but in the last two pics I have two examples of city+country, does it make any sense since it's only an online shop and there is a chance that I can also move abroad or something?

Thanks,

B.
