I have always done my best to 'buy well'.
Use an old respected comprehensive value guide, and combine that with eBay records and recent auction records to adjust the book value for the particular coin you may be interested in.
I have Krause World Coins covering the last four centuries, and Coincraft for English and British coins from 1066. MA Shops is good for European Medieval, and Coin India is good for current pricing on Indian coins covering the last 2,300 years. I still use a 1970 edition of Charlton for Canadian coins!
I have all copies of Sear for Greek, Celtic, Roman Republic, Roman Imperial, Greek Imperial and Byzantine
for comparative pricing with time adjustment, and then I look at VCOINS for current market values, including for Islamic coins. Also for Islamic coins, have a good look the the Stephen Album website - he is arguably the most knowledgeable Islamic dealer, and has written books on the subject.
I look on line at current auction catalogs before attending view days for the auction.
It is at the view day that I submit a single written fixed priced bid for any lot that I may be interested in.
Spend a lot keyboard time doing coin and price research.
My strategy:
1. Do your coin and price research first.
2. Examine each coin in hand first, consider the grade and make your own grading adjustments on that grade before considering to buy or bid.
