I have seen the video of both and they are almost the same. Except for the coins that are used. Please tell me which one of them should I buy.

Here's my two cents... Both effect are good, but the biggest difference is that one can be done in the spectator’s hands (gold and silver)! In my book this makes it far superior to the any effect that the magic happens in only my hands. Either effect is a good starter effect!

Mark, are you sure about doing it in the spectator's hands? Having sold Gold and Silver, I had thought it was the same basic idea as the HH, but with fake coins from the start, to bring down the cost of making the gaffs out of real coins. The gaffs are set up in the same order, though, so if you can do this effect in the spectator's hands, PM me the details.
