Well if it's just for fun.

Harrow Ld= 12.5K (all of the other 4* AS prices seem ridiculous atm. Striker and Marina are definitely better, so they'd be worth more but he's better than Liu)
Krink ld= 1K
Sylvia Ld= 200
Futoshi Ld= 9K, between Fei and heitachi's prices
Bikini Joe Ld= 200
Tiwi Ld= 10K
Jaxx Ld= 750
Hopper Ld= 200
Travis Ld= 500
Naja Ld= 150
Bella Ld= 2K
Dudley Ld= 3K
Bonnie Ld= 5K
Lois Ld= 2K
Scott Ld= 500
Krazan Ld= 750
Dobbs Ld= 750
Valentina Ld= 1.5K
Andy ld= 2.5K
Lianah Ld= 1K
Gail Ld= 5K
Fhtagn Ld= 500

No clue. any number people would give you is purely speculative.
i guarantee that there are less copies of LDs out there than any other rare card there is. There are probably more copies of more recent Crs out there than LD cards.

lots of prices in the market do not make sense in terms of their play value. Taking guesses at Lds is pure speculation. Given that these cards would be considered very rare, the market value it would command is probably close to the bigger Crs.

Their prices would also skyrocket if you were still only allowd to get the once.

Too much supply how many clintz does most low level leaders cost ?

Just look at the Noels and Miss's. Sure, some come out in Packs too, but still a decent representation of how things could be priced. IE, some really cheap like Hawkins Noel, others more expensive like Miss Stella.
But seeing as people could only unlock one, I could see these being more easy manipulated by rich players

@TGAP Trixie how would lianah be 1k if she is pretty much tiago with 1 damage and 1 star more around the 800 Mark for me maybe less

IMO it is better to assume:
what happen is Ld cards are normal cards like the others?

my prediction:
Harrow Ld (U or R): 3K-5K (can be more)
Kreenk Ld (U): 450
Sylvia Ld (C): 240
Futoshi Ld (R): 5K-9K
Bikini Joe Ld (U): 350-450
Tiwi Ld (R): 8K (look at Lola)
Jaxx Ld (C or U): 1K-2K depending if he is common or uncommon
Hopper Ld (U) this one is tough.. maybe around 800-1K
Travis Ld (U or R) another tough one: can't say for sure, maybe 600-1K
Naja Ld (U): 300-500
Bella Ld (C or U) 350
Dudley Ld (U or R): 4-5K (can be more)
Bonnie Ld (R): 15K - 18K
Lois Ld (U): 2K
Scott Ld (C or U): 800-1K
Krazan Ld (C): 250-350
Dobbs Ld (U): 400-500
Valentina Ld (R): 1.5K
Andy Ld (U or R): 2K
Lianah Ld (C or U): 300-400
Gail Ld (R): 2K-3K (can be more)
Fhtagn Ld (U): 350

There will be rich players who'll buy a bunch of them then their price go skyrocket like craZY.
