Seems the average sales price is like ~$20-30 more than you’re offering on both cards (Just a quick glance at both PokemonPrice and PSA Auctions Prices) - usually one would offer slightly more here, to attract someone with the card
PWCC has an auction right now for the PSA 10 Pidgeotto and Farfetch’d. Also you can check PSA website for auction prices. The Pidgeotto has an average selling price of $185 for the last six auctions.
I just recently found out about pokemoprice.com and PSAcards auction page but my reasoning behind the prices was initially based on searching for sold items and taking out eh eBay fee.
I just picked up a Farfetch’d PSA 10 for $85 including shipping (on eBay) so I don’t mind paying more than 70 - if you have either of those cards do let me know as im still interested
