ive sold a couple pcs on mercari and insta for reference
>how do you prepare?
if you want to start you should invest in: toploaders, penny sleeves and thank you cards. depending on where you sell, you can either ship with stamp mail or send tracked. if you’re selling on insta for example, you should provide video proof of the actual card (with flash on +mention the condition if it has any imperfections), packaging of the card and sending it out.
>how do you determine the right price?
it varies where the photocard is from, if the group is dead or not, or if it’s a limited time card. theres bit of a photocard hierarchy when it comes to pricing, album pcs don’t hold the same value as preorder benefits and so on. I’ll typically price album pcs around 8 ~ 10 usd and maybe around 15 usd if it’s an out of print album. for pobs depending on how recent the era it’s from, i price them between 12 ~ 20 usd. i do know sm offers kihnos of their artist’s albums but that’s more expensive so you would price that a little higher than regular album pcs. you should look at instagram to compare prices with since there’s no fees or tax, prices on sites like mercari and ebay are inflated because of fees but if you do happen to sell on those sites you should consider adding an extra few bucks if you want to make a profit.
>have you ever had a pc take awhile to sell?
yes ive had a couple pcs not sell at all, i tried to put a new listing for them every once and while for 3 months and nobody wanted them. thats normal for cards of less popular members you kinda have to keep putting it out there for someone to buy but it’s also a matter of using the right tags when posting and providing information on how you go forth with protecting the pc during transit. packaging is huge when selling, some people will refuse to do business if they don’t see the seller sending out their pc in a toploader and penny sleeve.
if you have any more questions or concerns i’d be happy to provide input
