Why do some Dealers regularly overgrade their coins - this sets a poor example to all and gives some potential buyers the wrong idea on grading which they may perpetuate, certainly if they buy such a coin (at an over-inflated price) they will expect when they come to sell it on to obtain a price relaing to the grade at which they bought it. A regular offender is R Ingram Coins as can be seen for their listing of an 1888 Double Florin with an inverted 1 for I in Victoria graded as 'Prooflike' with an asking price of £550 - link below. Caveat emptor !!!!!
