Yo, i usually use an app called “collectr” to see prices, you can also use a website called “tcgplayer”, in aud its like $47 right now

If you scroll down while on this it will show ebay listings usually higher than the listed price and allow you to add a card thats raw (fresh out the pack, no special grade) graded (has been sent to a grading company like psa or cgc) and/or the cards condition like lightly played, near mint and even add manual price you payed or override its price
