Selling item dilemma

[Soubriquet]

I collect a well known toy item that retails from £6.99 right up to £100+ though I don’t have any that pricey.

I’ve decided to sell up as I want to collect a different item.

There are dedicated facebook selling sites specifically for this group so I know I can sell them easily, even if I don’t make back my money.

Here’s where I’m torn.

Dd (7) used to collect these toys, which is how I got into them.

She sold up last year because she was bored of them and wanted something new.

She has asked me if she could use her pocket money and buy one from me.

I think it’s sweet she is offering to buy one instead of asking if I will just give her one

Do I:-
A) sell them on the fb group anyway and let her buy one brand new
B) let her buy it either at the price I would like or heavily discounted
C) just give her one as she offered to pay for it

Just give her the one she wants and sell the rest. Have you told her you plan to Sell the collection?

Is the collection incomplete without the one she wants?

She knows I plan to sell the collection which is why she offered up her pocket money

Two specific collections would be missing without the others, but the rest are all randoms and she wants one of the randoms. Actually she wants about 5 or 6 but is only willing to buy one

She is starting to learn money sense
